Soberella, we are not the same all of us, but I came to a place where I was unconditionally sober. I decided that if I were really sad, no drinking. Really happy, no drinking. People drinking around me, no drinking. If I were alone, no drinking. Spiritually satisfied or spiritually bereft, no matter, still no drinking.
I decided that there could be no situation or feeling or thought that could ever make me drink. Like Greenwood, I made it into a question of morality for me. A moral imperative fits the bill for those characteristics, so I guess that is what I did.
As for vigilance, what exactly would I be watching for? I don't think I am complacent about drinking again, I am just done with it.
