# of dives
50 - 99
I am Naui Certified from when I was in my 20's. I had open water 2 and one advanced course in ice diving completed. Some recreational diving in the Caribbean but most of it was cold water diving as a young enthusiast. Looking back. I was a relaxed , fit, normal weight diver who never used much air, trained but had the youthful indifference of "nothing will happen to me". My deepest dive was 85 feet. Common dives were 30-60 ft. I got re-certified with Padi a month before the trip. in the time frame from my late 20's till now (48), I had not done any diving. I had one minor incident on the second checkout dive. Which I spoke to the dive master about. She brushed it off as Vertigo. It was a 9-11 ft dive in a very murky channel. You could barely see your hand in front of your face. upon ascent, maybe 3 feet from the top. I suddenly got very flushed, hot, and felt like my head was swimming. I would not have been capable of looking at my gauges. pop! up on the surface. gave it a minute. felt fine.

Before this trip. I did have a medication change. i have knee problems, and was taking diclofenac sodium (a NSAID)along with pepcid (the NSAID causes grief). however I think these 2 medications, messed with my thyroid levels. This is a replacement hormone I have been taking for 10 years. however the dr. added T3 to the mix. looking it up, this can cause anxiety issues for some people. I choose to stop taking the diclofenac and pepcid while diving for the 7 days. I didn't want anything that could mask the pain of getting the bends.

I had booked a 7 day live aboard trip after a 8 day land trip in Sydney. I am 5'7", 230 pounds, and a BMI of 35. I had recently lost 45 pounds and am still in process. I gave up the dieting for the trip. I was still eating the healthy meals provided. I was also trying to drink water on a regular basis. As well as coffee. I had taken Dramamine before boarding :) First 2 hours on the boat. I had motion sickness. Vomited, was given 2 Quells. overall I would say I was pretty solid after that. only took Dramamine one more time.

This was my first stupid mistake. second day of diving. I had a camera and got carried away taking pictures,I stopped looking at my air, or gauges. I was at 97 feet and had 70 bar! My dive buddy was waving me up! I started to hustle. If I was on land, I would call it a very purposeful fast walk. I felt worried. I knew I could not shoot to the surface. I started a steady climb. my dive buddy was too far ahead of me, and I could not reach him. I am now at 55 feet! ugh! keep going. 45 feet. Where is my dive buddy?!! Turns out he stopped, to take a picture with the boats photographer. I am watching my air go down. finnally 20 feet! I am at probably about 20 bar of air. I opt to do my safety stop. Tapping my gauge, nervously watching my air. c'mon. c'mon. as i finish I see my buddy. We motion to ascend up the mooring line. I ascend in a slow control manner. meanwhile my mind is going : oh my god! hurry up! relief at every fsw that goes by. I inflate my BCD on the surface. 0 bar reads on my SPG. 97 foot dive. Crisis averted. I am embarrassed. My dive buddy is holding it back, but I can tell he is upset with me. I never told him, how close it was for me, but I apologize profusely. telling him I will never do that again. I did speak with one older guy, a former instructor and told him what I did. He proceeds to tell me he made the same mistake! Got carried away with what he was doing, and forgot to watch his gauges! I am thinking, wow! dive instructor! I was shocked at how easily you can loose site of your depth. I mentally vow to stay with my buddy. dive with a dive master, and watch my stuff! I THANKED MY LUCKY STARS!

I also discovered that I don;t breath like I used to. I did not feel as relaxed either. The dives were easily deeper on a consistent basis, 60-80 ft on the GBR, and later 85feet or more on Osprey. There were a few opportunities to do some tunnel diving. Did I feel anxious? maybe. I might say it felt like I was pushing myself to go beyond a little of what I was comfortable with. there was one day when the current was so strong, they had to send out the dingy to collect every single diver. At least two divers got stuck in a tunnel, because they went in the wrong tunnel. they wiggled backwards to get out. I felt like I was normally breathing for like, 6 breaths, and then I had a huge compelling need to breath really deeply. like really fill my lungs. repeat. This equated to me have dives of 30-35 minutes, when other divers made it for 45-60 minutes. i recognized this and tried to work on my breathing. but it never changed. I wondered what happened to the girl who did it without thinking? I also struggled with buoyancy. I was always trying to get my feet down. and when I was on the bottom. I would have to add air to my BC. I am thinking now, that I was overweighted.

All in all we did 7 days of diving. I dove most days 3 dives. maybe two days 4 dives. first 3 days it was a NITROX mix of 32%. the last 4 days ended up at 33%. Every dive I completed a 3 minute safety stop at 15 feet. most of my dives were never more that 35 minutes. Due to my air consumption. I usually had a slow descent, due to the fact that my ears will not equalize with the val salva maneuver. I have to stop breathing, swallow, and then they will go.

Day 7, first dive of the day. During the dive brief and after my wetsuit is halfway on, i feel like I am getting motion sick. I go back to my cabin, and take a Dramamine. in hindsight this was probably not wise. I finish gearing up, and do a giant stride off the back. This will be a straight drop down, due to currents. Not down a mooring line. The Visibility for the first and only time, was like glass. most of the rest of the trip the visibility wasn't as great due to the full moon. I got in and started to descend. all is going well. I OK signal to my dive buddy. there is one other couple with us, and a dive master leading. we Ok a few more time, I am watching my depth go down. Then I am thinking. Wow, this is really BLUE. And wow, I can't believe how easy this is? (usually I am working on my ears) they didn't seem to bother me at all. I am guessing this is somewhere around 50-60 feet. those are the last numbers I remember. The dive master tells me he thought I was dropping too fast. My dive buddy thought I was normal (dive buddy has 18 dives). I turn to find my dive buddy. i can't. i roll over, maybe he is on top of me. Nope. I don't see him. I see nothing but blue. I look at the gauges. 97 feet. 97 feet?! I feel confused. What happened to 55? I look up. I see the bottom of the dive boat, it appears close, maybe 35 feet. But the dive people under it. look like ants. Weird I think. look at my gauges again. 91 feet. oh. it looks like the dive master is going back to the boat. I wonder why? I start to swim torwards him. gauges again. 97 feet. no. 91 feet. this doesn't make any sense. Why is the image of the boat and divers not moving? I am now swimming hard. ugh. I have a weird thought in my head. Am I alive? wouldn't the picture of the boat and divers change? I am so confused. Why am I swimming up and the gauge keeps going down to 97? if I was dead, wouldn't somebody have grabbed me by the BC? So confused. then I have a thought. something is not right. me. i am not right. Now I start to feel panic. before I was just confused. Ok. What to do. I cannot tell you the effort of mind this took me. I had to tell them I was crazy. I am now breathing like a freight train. keep the regulator in. I make the crazy sign beside my head. I have no idea where anyone is. I can't see anything but the little ant divers. I cannot see my gauges. I think the little ant sees me. I think the ant diver turns. I start motioning for him to come here with my hands. I motion faster, I breath faster. I cannot see anything now. Is someone coming? I am scared. I feel arms. OMG! I feel arms. Someone has me. has this. hands on my elbows. the most comforting feeling in the world! breathe. I grip his arms. i feel like we are going up. ok. breathe. breathing. lots of breathing. suddenly at 40 feet I can see. I can see the dive master looking at my gauges. still holding my arms. I am gripping his. I know this is 40 feet because I noticed it on the gauges. 30 feet. feeling better. loosen my death grip. 20 feet. he signals 3 minute safety stop. I signal back. Ok. I am good now. Normal ascent to the surface. He raises his fist for a dingy to pickup. and I gratefully get in the boat. strip of my gear, and go upstairs and lay down on a lounger. My SPG read 100 feet (never saw that number) and 13 minutes. The other divemaster. called it 13 minutes of education. I ended up talking to that first customer/dive instructor who said I should probably go back in for an easy dive just to kind of get on the horse again. I did in fact do that. I went for 2 dives 60-75 feet. With no incident. was a little nervous? yes. was the dive ok? yes. was is the best idea for me? probably not physically ( i have barotrauma in both ears and vertigo now) mentally, maybe.

I asked what the others saw. the divemaster said he saw me drop fast. this made him uncomfortable. he said he was swimming back, and says he was maybe 10-20 feet ahead. he tells me the other dive buddy and couple were above me. They all said they saw me make the crazy sign by my head. The 3 of them were trying to get the dive masters attention. my dive buddy and the other couple did not know what to do. I f I was not with the dive master I would have been in trouble. probably dead. The dive master had seen my signal and was swimming back quickly,. I asked him what he thought at that moment. He was like "oh ****" . he didn't know. however he did great. And I am beyond thankful. There was no other conversation about this with any of the staff. I did talk about it a little with other divers in an effort to understand. I am still at a loss.
 
:narcosis:Martini's Law:confused:

For every metre past 30m is equivalent of drinking one glass of Martini. The effects of narcosis.

I have a deepest dive of 46m, narcosis central for me. Yet I have also had narcosis at 32m. An individual can get narcosis at varying depths depending on physiological factors, age, fatigue, medication or ambient conditions.

Although you were using 32/33% it might still be narcosis. IMHO I would say it was the meds with a slight touch of narcosis considering the rate of descent.
 
Happy it worked out for you. When you were describing the ant divers I had to laugh...my narcosis was the same at 46m. everyone, everything was ant size except the narcosis and my signal of same.
 
Not wanting to flame you, but I cannot understand people (mostly Americans) who come to dive the GBR and have so little experience, especially on a trip like you did that includes Osprey Reef. Why not get more experience at home before the trip? Too many people come here and either have very bad experiences (like you) or die (like Tina Watson).

By the way, I would not consider leaving the bottom at 70 bar at 97 feet (27 m) too low an amount, at least for me.
 
Thank you for sharing this with us.

Not sure it was nitrogen narcosis. I simply think that you are lacking some basic skills and went behond your confort level. You were NEVER closed to your Buddy in the two dives that you are describing. This is your fault and your buddy's fault. To have a dive buddy with 17 dives, and to descend in the Blue is a call for disaster. I think that you have been VERY lucky.
 
It's ok for the flaming. I deserve it. As for the experience I agree with that too. I should have dove all summer. the trip to Australia, ended up coming together quickly, and without question I needed to be in better shape, and more comfortable with diving, it had been too long. I also experienced sever motion sickness, starting 2 days after dive. Which now I attribute to the barotrauma to my ears, which undoubtedly happened on the quick descent. I am surprised by that, as I never had pain, on the descent, or at any time after. But the ENT saw dried blood and fluid. And severe motion sickness could possibly be An understatement! I am now 3 weeks out and 90 percent of it is gone. I also feel like I had an undercurrent of anxiety on this trip. And definitely anxiety after. Even hands and feet tingled.? This has also completely gone away. took 3 weeks. Low T3 levels also causes anxiety I have since learned. Since diving I stopped taking the Pepcid and nsaid, which interfers with T3 levels. I will be curious to see blood work in a month, to see if it rights itself. I had a never experienced anxiety before. Certainly this incident and diving beyond my levels could have induced it. It also could be completely physiologic. I was unbelievably fortunate, and learned a great deal. So outside of having prepared myself better, not doing a medication change before a trip like this, dive my limits, and increase them SLOWLY ( not jump right into osprey), stay close to your buddy, get in better shape, read this board, to learn from others mistakes, I did learn that even though I felt panicky, I did hold it together enough to help myself a little. And consider your buddy. All 3 buddy's did not know what to do for me on that second dive. They all just tried to get the dive masters attention! If he wasn't there it would have gone south really quickly. And I have read so many times here, how you shouldn't just depend on them solely either! I feel like, reading these boards, and my experience, educated me more than a decade of diving did before. thankful for the input.
 
Very good reaction.

Maybe a last point from my part. Especially when you descend in the blue, YOU SHOULD NEVER be deeper that the DM and stay with your buddy. The same thing applies while going up.: not much lower that the DM but NEVER HIGHER.

Take care :)
 
Thank you for sharing this with us.

Not sure it was nitrogen narcosis. ...
May not be the primary issue, but at nearly 30m it will have been present.

Just like alcohol, I can have a skin full and feel fine (I my drunken opinion) or just one beer and feel cr*p. NN can hit the same way.

Ditto. We were on the SOF a couple years ago and one diver had a total of 4 previous dives. My wife and I were on 200+ and were by far the most experienced.....to the point we basically dove without a dive master as they were busy herding the rest. And like many of us the more I dive the more apparent it becomes I don't know it all......not even close.
