I don't drink, I'm not allowed to on my probation terms, I also have to sign up for a substance abuse class. Alot worse than it sounds, just busted for violation involving alcohol and now I have to do all this stupid shit, including community service.
I see nothing wrong with a case a day, unless I had a beer gut. I like liquer though, so I drink over the rocks.
The only time I see it is considered out of hand is if it is causing a problem with you meeting bills or other important things in your life.
