I've never had a drink of alcohol in my life. Not even Nyquil! Of course it can be a little difficult sometimes. I'm in the Navy which has a definite social drinking climate. Most people are pretty tolerant though.
I've just never felt the need to drink or wanted to give up control to anything. I am a Southern Baptist and born-again Christian but that doesn't factor into it. My church does frown on the consumption of alcohol but there is no pressure for abstinence.
I've gone 32 years without it. No need to start now. Besides, all the money I save by not drinking goes straight into the Disney Vacation fund!
