I had something similar to this when I did my dive cert. out at a night club till 7am picked up at 7.30am in the water by 8.30 entered the water without a wetsuit (surfers) instructor aaas I was loco once I descended I saw why I froze for 40 mins and felt like I was going to spew in the reg the whole time I put it down to the kebab I ate as alcohol has no adverse effects that I am aware of and is good for you...
