Not a good idea
When I worked commercially one diver had smuggled a bottle of vodka into the sat chamber and consumed most of it one day as we were unable to dive due to weather, and we could not put the bell down.
I am not sure how much effect was pressure related, the chamber was at 120M, and this particular diver had personality that was rather aggressive at the best of times. I had having traveled with him a few times and he was not what I would say was an ideal traveling companion either. I was on the outside in charge of the sat system, but there were three other divers inside with him. Before he did anything crazier than get drunk and behaving like an ass, I had the other divers restrain him and take him into another chamber in the system (that we had to use to blow down two more replacement divers) to take him (and his buddy) out. Deco was more than 48 hrs IIRC, and of course he was sober when he came out. He never dived with us again.
