Welcome to SR.
You don't have to drink every day to be an alcoholic. It's about control. We alcoholics have lost control of our drinking. Try going for a month without a drink or better yet a year. If you don't want to wait that long try controlling the amount you drink. For the next month just try having 2 bears every other night. Or just try having a couple drinks the next time you drink. It's the inability to stop once we have had the first drink that separates us from "normal" drinkers.
It's nobody's place to tell you if you are an alcoholic or not. Try what I have suggested then be honest with yourself and you decide.
