You would not have coped very well on the liveaboard I was on last year then - the briefing for the first dive was 6am with the first dive at 6.30 so it was a 5.30 wake up call every day (6 days on board). To make it even worse, the guide was extremely happy and cheerful all the time even at that time of the day . I was ok though as they did allow at the briefings so I was probably awake about 5 mins in.wake me up at 5:30 2 days in a row and I'll bite your head off and then fall asleep underwater...
