Reasons for not drinking alcohol

I don't drink alcohol. At all. I used to occasionally have a little, but never liked it much, and then I had an alcoholic girlfriend, which put me right off the stuff for good.

John Scalzi covers his reasons for not drinking in detail, and lots of people in the comments chime in to agree. Some of it applies to me, some of it doesn't, but I'm so glad he said it and people are talking about non-drinkers.
