I'm worried I may be becoming an alcoholic, what are the signs?

i absolutely love the feeling alcohol gives, i dont get hangovers anyomore and i tend to stay in a constant state of drunken bliss every time i go to my cabbin on the weekends.
i know its bad for my liver but how bad is one weekend every so often?
i also haven't been drunk to the point of amnesia since i was 17.
