Hey Silencer,
You've already started. When I was 21 (I think you mentioned that on another thread) I had no clue about my alcoholism. What a great life lies ahead for you if you can stop now.
I wouldn't wish on anyone the misery that I went through. You've got the whole world at your feet - the keys to the kingdom - if you can stop now.
Give yourself and those who love you the best Christmas gift ever - stay sober. You will be amazed at how your life will change.
AA was the key for me. Its worth a shot.
Mike
