janeeb -- I agree with everything effortjoy said....
I would also add -- Play the tape. Play through what would happen if you did drink. Not the "fun, relaxing" part that we all romanticize it to be, but the nasty, messy, ugly part that comes once we cross that line. Play the tape through to how awful you will feel tomorrow morning with a hangover and mentally and emotionally hating yourself. Play the tape through to how awful withdrawals are and how you never want to go through them again. Play that tape until the urge passes... because it will.
Hang in there! Keep reading and posting on here. It really is a godsend.
