I recently realized my dad is an alcoholic, and I would really like to help him, but don't really know how. Apparently my mom has been trying to bring the issue to his attention for about a year now, and he doesn't really seem to think he has a problem. He's gained a lot of weight recently, and he has one or two gigantic glasses of scotch pretty much every night. The thing is, he is apparently a 'functional alcoholic'; his drinking problem doesn't get in the way of his job or other things for that matter, but I (and other family members) have noticed that it's becoming a health issue. I would really appreciate any advice you guys could give me.
