Yes you are probably alcoholic, but only you can know for certain. Blackouts dont happen to "normal" drinkers. Alcoholism is like diaherra, its in the jeans. Meaning its in our genetic genes, passed over from generation to generation. Who knows or can pinpoint the time you became alcoholic, you are now a pickle, you can never go back to a cucumber. many treatments out there to choose from. If I were you, I would pick the best treatment with the best success rates out there. AA comes to mind. Best success rates, ONLY if you work the program as outlined in our basic text book, which a text is meant to be studied.
