If the girl in your AVI is working the bachelor party, it appears you won't be needing any booze to make her look good.
I am taking Mass Fx right now and have drank more than I usual do (as I rarely drink) in the last two weeks. No issues for me, it's quite the stack actually.
Drinking is stupid in that it negates or at least slows down your gains substantially. That's why I try to reserve it for occasions like weddings, etc.
