Or am I confusing that with being narced?

Or am I confusing that with being narced?
You're more likely to end up buried than in the hospital. Seizures as a result of OxTox are not particularly harmful aside for the small and unfortunate side effect - spitting out your reg and sucking down water...I was gonna say that diving nitrox beyond the MOD will either get you in a hospital or in a graveyard, but you beat me to it.
One of my main fears when diving Nitrox is a strong down current. Mainly cos I tend to end up around 30m in strong currents, tho usually on 32 rather than 36. But still around the 1.4 area. Which is very safe. But wouldn't be ten metres lower. That is my main reason why I have to think about whether to dive Nitrox or not.
Really it's a very specific depth range. Between 20 and 30m it rocks. Shallower than that what's the point given the expense. Deeper than that you need to rethink. So in that 10m zone (which for recreational diving is a BIG zone) it's great.
Personally I love it but when I get near the limit it does up my anxiety a little.

If you feel narced, ascending slowly is supposed to help "clear your head" pretty quickly. I think the onset of oxygen toxicity is sudden loss of consciousness and involuntary seizures. It's hard to self-rescue from that.
90ft and below, Air only for me.
Not to mention that ascending won't necessarily stop or prevent a seizure.
People have toxed well after leaving the maximum PO2.
Interesting... that's close to the depth (120+) at which I'll no longer consider air as a viable gas.
If you aren't at 100% of your O2 Clock and simply a CNS seizure from a high PO2 then ascending will likely reverse the seizure.
...Question: Is there any reason why I should not use Enriched Air for every dive? Is there a reason why I would want to sometimes use AIR opposed to Enriched Air?
From my studys in the Nitrox class it seems ok for me to just stick to Enriched Air whenever I can...
If you aren't at 100% of your O2 Clock and simply a CNS seizure from a high PO2 then ascending will likely reverse the seizure. If you've been diving on EANx all day and you're pushing 100%+ O2 toxicity, you probably even run the risk of seizing at the surface.
Sorry, I meant to Rec dive limits.
