I've heard that theory before, that "you're an alcoholic if you feel the need to drink alcohol periodically". Like, if you drink one beer per day during weekend, you're alcoholic because you feel compelled to do it, periodically/ on external stimulus ("it's weekend"). While this may be a theoretically sound definition of "alcoholism", to me this sounds weak/ not anchored in real human perception. I argue that if it has no significant negative effect on your life, it's not addiction/ disorder.
