As I've said in a few posts, I actually believe that trying to moderate - and being honest with yourself about your success in meeting you moderation goals - is a very critical step to being willing to accept one's alcoholism. I often tell others that they are well on their way to recovery because they have now learned that moderation doesn't work for them (what I call Step 0 of the 12 steps). So, rather than view it is failure, just view it as you now knowing another thing that doesn't work for you.
Now you can begin a new life -- starting with today.
