Alcohol problems arent about how much an individual drinks, theyre about how they affect your quality of life.
Its sounds like Topspindocs life is just fine so no alcoholic.
Sure mate. Topspindoc is only 27, he can drink until he passes out and still he wouldn't be much worse for that. Keep doing that until you are 47 or so, and you will see what it means, however there will be no turning back then.
