Very, very respectfully I would suggest that the following is not anything like functioning at all. I was exactly where you are now for years-- this is pure, 100 percent, alcoholism and IMHO it's going to get worse-- much worse. Alcoholics are alcoholics-- calling it functioning, in my opinion, is simply a way to make it seem it's not as bad as it really is.
Please consider starting Alanon meetings which are for people who love, or have loved, alcoholics. Though I am not religious at all, and don't consider myself spiritual either, and I sure as heck do not believe in God, Alanon still saved my life.

He did well but since December 1 he's come home belligerent once and I found him this morning drunk on the driveway at 6am.
