It's in the eye of the beholder I suppose. I wouldn't consider that bad, but that's coming from a former hope-to-die alcoholic who would drink around a dozen units of alcohol on any given night. I also know others who drank at about that level. I was able to keep up a job at a tech company as well, though I'd say that job was degrading my life and the alcohol was more a result of that than the other way around. I'm certainly not under the impression that it was good for me; I don't drink at all any more.
