In the first month or two, spend some of the money you would have spent on alcohol, on something you want or need to promote your new sober lifestyle.
Post on the gratitude threads everyday for the first month or two.
In the beginning do whatever it takes to distract yourself from cravings. The thoughts of using come MUCH less frequently over time. (But if you use again even once all those craving thoughts return with a vengeance. Why make yourself go through that?)
Remember how difficult quitting is, so that you never put yourself through it AGAIN.
