You obviously know how to not drink; you did it for 55 days. Take a good hard look at your recovery program (no, I am not talking about AA) and see where the hole is and patch it up. What was going on with you before you picked up that first drink? How were you feeling? Why were you unable to utilize the mental and spiritual tools that had gotten you this far?
Answer these questions honestly and make the changes necessary to your spiritual growth plan. True sobriety starts with not drinking, but that is only a very small part of it. The real work is changing how we look at ourselves and the world around us.
