Thank you sj, I have yet to have that talk with him but I know we need to have it. Everything has been calm again since that night, I don't know what got into him to act that way. He gets unpleasant when he drinks but never to that extent, really. At least it doesn't happen often. Maybe it was the mixing of different drinks, or maybe he felt exceptionally down before he started drinking, I don't know.
Ready2Change, thanks for your post. I never have a conversation with him when he's drinking, I go to my room and leave him alone. That usually works but not always. Again, it depends on what's going through his mind at the time.
When he comes to bed and I'm still somewhat awake I try to pretend I'm asleep. Then I hear him talking to himself. He is mostly expressing anger at God for what He did to him (his perception) so he curses at Him. It gets pretty ugly but I know that God can handle it, in fact, I'd rather have him talk to God than anyone else that way.
