My husband self-medicates with alcohol. For our area he earns a pretty good living, pays the bills and plays with the kids these days. He'll pick them up or drop them off if needed.
The kicker is that if he's not busy doing something he's drinking. We were both home last night and have $120 for the next two weeks. So far he's made sure he's gotten some movies for us to watch, bought cigarettes, chew and beer. I'm sure he'll make sure to have more beer before he gets paid again, plus he's planning on buying a $200 gun this week.
I'd consider him functional, but not a lot of fun for me. I hate his drinking because of the manipulation, verbal abuse and bickering that it causes between us. He however is convinced that his drinking does not cause a problem, but it's my fault we end up fighting because I get to uptense. He says that if he said some of the same things sober that we'd not fight, but because of the alcohol we fight because I have issues with it.
