Yeah, I do the same. But you don't want to go overboard, otherwise you'll become a trainwreck. I would probably have a bit of a harder time attempting to socialize properly if I didn't have any alcohol at all for an extended period of time.
If you get too drunk, you either get so tired that you nod off or you **** up your speech enough that you're more likely to get judged in an undesirable way.
Funny enough, I've had those specific instances happen to me blatantly, and I'll wind up trying to redeem myself/explain myself to the other person, only to make things even worse.
