I am a bipolar alcoholic, on a similar mix of medicines. First, the medicines do not work when you are drinking. It's a fact, and I have experienced it. Second, I believe he has to give up alcohol in exactly the same way and on the same terms - total abstinence - as any other alcoholic. Somebody could say - "Oh, the poor guy; he has two problems" - this is a trap. He has to deal with the alcohol first. It's hard, but that is no excuse for not doing it. You should look out for yourself. I used to take advantage of my wife's longsuffering sympathy for my problems. That's what alcoholics do: anything to keep drinking. It wasn't until she really was halfway out the door - for real - that I got a clue. Best of luck to you.
