Sounds ok if he doesn't have a family history of liver issues. If he does, I would scale back in a big way. Though personally I'm an occasional social drinker - feeling like you need alcohol every evening never sounds like a good idea.

Sounds fine to me. That's not that much.

My DH got the habit of drinking about 2oz. whisky every night. He doesn't get drunk but I feel concerned for his liver health in the long term. Could anyone give an opinion about what would happen to his health if this habit continues say next 5 years? Btw, we usually have a glass of wine at dinner.
