Well it sounds like his life was a complete mess when he was drinking. And it got better when he stopped. Look most of the population seems to be able to have a drink and leave it alone. I'm not built that way so I don't drink at all. Some problem drinkers learn to moderate , most don't. Drinking like he did is dangerous. Most normal drinkers dont abuse their mates and smash up their homes. I wonder why he feels the need to tempt fate. He must think that there is big magic in those wine bottles and his life will be miserable without it. I would be conceded too if I were in your shoes.
