Alcohol doesn't make you feel crappy. It makes you feel good. That's why people drink it.
And, in moderation, one can get a mild buzz without the hangover.
The issue lies in one's self-control and susceptibility to addiction. There's a variety of "drinkers" out there. I've got a friend who can't handle more than two beers, and set a hard limit there. I have a friend who drinks non-stop. No exaggeration. Both have totally different responses to alcohol, too.
