You can argue the semantics of "an addiction" versus "a problem," but it really just comes down to being a functional alcoholic versus a full-blown fuckup. Neither one is healthy.
I'm all for cutting loose and having a good time somewhat sparingly, but drinking daily (anything more than a beer with dinner or something to that effect) is really not good. Just because there are no social or career consequences doesn't mean it's ok.
And no, I'm not talking out of my ass. I was a 60+ drink per week guy about a year and a half ago, and even though I never ran into any repercussions apart from shitting on my body, I really regret doing that.
