I know, I chain-smoked since I was 15, and only managed to quit for good about five years ago. I'm terrified of becoming hooked on prescription pain killers, and usually only take them when the pain is intolerable or I have to be comfortable to accomplish some particularly demanding task.

I used to drink a lot until I got married. Now I can take it or leave it, I'm not an abstainer, and I enjoy the occasional snort, but sometimes I go for months without having a drink. I realize now the urge for alcohol was mostly an excuse to go into a bar to pick up women.

I try to limit my drug use now to the strictly recreational.
