I was basically drunk for 12 years, and somehow I managed to climb out of it; I don't know why. Why did I get well when so many other people don't? It had nothing to do with any virtue on my part; if I were Christian, I'd call it grace. I just got lucky. Mostly you just get tired of it. So when you get sufficiently tired of it, you either descend into utter obliteration or you get out, and so I got out.
