I wont to add that doing a 5th with your sponsor is very critical. there is lot written for this step in the big book.Figure out the short-comings/character defects via the 4th step and start addressing those and also start making amends and work the 10th (watching for the short-comings to keep coming back). You will find the power to overcome this spiritual malady.
We think we have done well enough in admitting these things to ourselves. There is doubt about that. In actual practice, we usually find a solitary self-appraisal insufficient. Many of us thought it necessary to go much further. We will be more reconciled to discussing ourselves with another person when we see good reasons why we should do so. The best reason first: If we skip this vital step, we may not overcome drinking. Time after time newcomers have tried to keep to themselves certain facts about their lives. Trying to avoid this humbling experience, they have turned to easier methods.
Perhaps this is the main reason you are slipping. Scoot up some courage and go through this humbling experience and you will find the power the book talks about.
