@Walter Hinteler,
Yeah, the health issue is clear. High blood pressure, etc.
As for outright alcoholism, I think there's a lot of people who misdiagnose themselves based on faulty criteria. I'm thinking of two of my current friends. Both have identified themselves as alcoholics. Years ago, they would both drink often and to excess.
Then the first one got married and cut way back, except for when he was fighting with his wife. Then his baby daughter was born and he hasn't gotten drunk since. I don't think he fits the criteria for alcoholism because he and I can have a beer with lunch or a few on a weekend night and then he goes home sober.
The second doesn't drink so often anymore, but when he does, it's until he's sloppy drunk and passes out. He says he's an alcoholic because he can't stop once he starts. I'd guess he's more likely to match the criteria.
