If not drinking will spoil your night, you have a problem.

I understand exactly where you are coming from, and perhaps my view on this is because music to me is about enjoying myself and stress relief, not a job, (even when we play weddings).
But, even when I do play larger well paid gigs, the organisers usually say 'round of drinks for the band' as soon as we are set up and waiting to play. Of course, that doesn't necessarily mean alcohol, and I've enjoyed myself without it countless times, but just having one alcoholic drink can make it a little less tense. It's all about knowing limits; I wouldn't get drunk.
I am just a musician for the fun of it, not for a career in it, so my viewpoint may be different.
