This is a rather common expression, "Moderation did not work". I used to follow a moderation group, that also had an abs side. I think moderation works for some heavy drinkers. What I did find from my observations and personal experience is that abstinence is a lot easier. It seemed the moderation thing was a lot of work trying to always keep within the boundaries and the occasional or oftentimes running into the ditch. Glad you know now and hang in there.
