AVRT is learning to recognize the self talk that happens surrounding one's addiction. I was just reading The Small Book by Jack Trimpey who wrote Rational Recovery - The New Cure (highly recommended if you are interested in AVRT) and he talked about doing something similar to a step 4, but instead of a moral inventory, one should do a self talk inventory. What are the thoughts that go through my mind before I pick up a drink or go buy some? What do I believe about why I am addicted? What do I tell myself about why I haven't quit even though I know I need to?
Personally I think that is a far more effective and powerful inventory to take regarding one's addiction! Instead of focusing on what a bad person one must be for getting addicted, one focuses on the thought processes that keep one addicted.
