I think this is a very important observation for lots of reasons. First, I could always not drink on a given night. But if I had a drink it was "game on." It's hard to believe how serious it was, but I've been cut off a couple of times--which shocked me because of course, you know, I kept saying, "I'm not an alcoholic."
The other problem is that if we believe that we just don't do it well a couple times a week, we keep trying to do it better....
