I also agree that remembering why you quit is a good tool. In addition, can you also figure out why you ever started to drink? Thay may also be very powerful. The reason that you started to drink is likely still somewhere within you and may still requires attention. Only difference is that now you can "feel" it and must learn to deal with it since the alcohol is no longer covering it up. Tough part is that some of us have a hard time understanding why we drank. Discussing with others may help us to figure it out though.
Just my $0.02 cents worth.
