A social drinker gives up booze for a month:

So what else did I learn after a month of stone-cold sobriety? That it's over-rated. There is a reason why people drink proportionally more the less they like themselves: alcohol takes you, as so much slang for drunkenness has it, out of your head. I’m no self-loathing Hemingway or Parker, but a month is a long time in your own uninterrupted company. Nobody wants to spend that much time with me--not even me. This is despite the fact that I found abstinence to be good for my self-esteem, not the other way round. People keep asking me if I feel healthier. I don't, particularly. But I do feel smug.
