Glad you have made the decision to quit Avice. Most of us couldn't imagine life without alcohol either, I know I couldn't. The reality though is that it's better without it, far better. It's initially tough but once you get some sober time under your belt you will wonder what you were thinking while you were still drinking.
I will play devils advocate and ask why you don't just quit now? What will be so different about to tomorrow that you can't just quit today?
