Keep a day to day calendar and X out every clean day. Reward yourself with treats and good dinners. When you discover how much more awesome your sleep is, you'll be more addicted to that then the alcohol. And start keeping the $$ you would have spent on the liquor in a special jar. When you get a good stash buy yourself a prize. Try to make it a fun, interesting experiment rather than an awful chore.

Take a pic of yourself now. Then compare it to how you look at the end of one month.
