That sounds familiar, too. One time my AH said to me "if my brother calls, and sounds drunk, tell him I am in bed because I hate talking to him when he's drinking." I took that opportunity to tell him I know just how he feels, because he acts and talks the same way when he's drunk.
There have been so many times that I wish I had video taped him when he was staggering around, bumping into walls on his way to bed. But for now, things are going well, and all I can do is hope they continue to do so. If a binge occurs, at least I know where my boundaries are and I WILL NOT subject myself to being around a drunk slob. I like myself too much for that.
