The longer I spend in cube-farmdom, that movie becomes both funnier and more sad...
But to the question at hand, there is a lot more to alcoholism than just drinking a lot. Some folks can drink like fish and by those markers - having it affecting them in various ways - don't quaalify as such. THen others drink comparatively small amounts, but it's still affecting them. Of course, to other people, having one drink makes one a complete lush.
Myself, I enjoy a beer or 2 many evenings. I do normally hold off until the kiddo is in bed before opening one. But almost as often as not, by the time that happens, and dinner is done (I work a weird schedule - we're eating dinner most of the time after he's in bed) and things are cleaned up, I don't feel like going down to the beer fridge / cellar to get one.
Same thing with my homebrewing, I don't have a kegerator, so I limit it to one tapped at a time. I usually plab to have one on deck for when that one kicks, and it takes a while to knock off a full keg. I do have a couple recipes that I still bottle, though those are as much out of sight, out of mind.
