For the average person non-excessive drinking is completely fine. I think it was Frank Zane who advocated 1/2 a beer relatively soon after his workout. A few studies have shown that alcohol actually increases free testosterone by a statistically significant amount, though I honestly doubt if it's really going to make a noticeable difference for most folks. If you're getting ready for a shoot or want to look your best on the beach for a day or two, then obviously it isn't going to do much good by ingesting empty calories. Though I'll admit it can act as a sort of carb load where I've drank and woken up shredded and full looking the next morning. I'd never use it intentionally for an actual project though. The key is, as usual, moderation. If you're drinking heavily every day and still look good you're either my age or younger or very genetically gifted. In either case I think you could look better without it quite so often. Yeah, I always look pretty skinny (especially with clothes on) despite having an overweight BMI. I've always been envious of the guys with just slightly narrower shoulders than me; their shoulders always look so much more powerful and they all seem to have bigger arms. Their shirts fit better, too. At work, a couple dudes thought I weighed 125 lbs. Keep in mind they're fat and clueless, but still... it hurt. A small frame with large clavicles is a gift from the gods. I've known a handful of people like this and every one of them looked amazing once they had any reasonable amount of muscle, partially because it seems that people with small frames have blazing metabolisms and put on minimal fat in the process. Embrace it. Bastard.
