For me, the most important litmus test is the faith, ability and will to not pick up a drink, ever, for any reason. Everything else is over thinking it. I believe all the stories that I've heard about people trying to be moderate drinkers. This isn't to say that AA and working the steps doesn't work, just that the first step is the most important one.
Today, once again, I am thankful to not have a hangover. This is going to be a good week!
