@Jason_Richard Prescriptions fuck up your liver just as much... I just have to make sure for myself (and the wife) that I don't go too much or that I'm ever "all day drinking"... I allot myself my time, and stick to it.
It's also helpful that I'm a lovely dovey drinker, and not violent... An overdrinking night for me is texting my friends to remind them how much I love them. Then I feel stupid the next day.
