Thanks so much for the reply. Pretty much everything you have said, I have said to him, so your comments at a minimum are making me feel less insane.
After essentially being an alcoholic for 40 years, getting sober was a great accomplishment for him. After failed AA and rehab attempts, I found him a "swanky" rehab with a great treatment program, and meds that seem to work for him. I guess when you are an alcoholic you never lose the desire to be "normal", even when life is going well.
I too was gigging over the "1 or 2 glasses of wine". 5 shots of vodka later...not pretty

I don't advise that on Doxepin and Celexa, for sure. He was lucky not to have stopped breathing, and while he didn't fall down or black out, he had very little recollection of a 12 hour period of time. If I was his psychiatrist I would have told him to get to the hospital.
I have no idea how this will all play out, but will keep everyone posted. I have to say it was nice though, not worrying about him all day, for almost a year.
