The AA big book, as it is known. It's actually a small, but very thick book. It's the basis for all twelve step programs.

The main exercises related to my comment are writing out resentments as they occur—who/what wronged you, why that hurt and what part we may have played. Same with fears—what they are, how do they affect us.

Honestly, a lot of it is so simple, but it really forces you to think about these things.

i always recommend Addictive Thinking: Understanding Self-Deception [Twerski M.D., Abraham J] on the topic. A short and insightful read that goes one level deeper than looking at any particular substance. He focuses on the contradictory thinking that addicts use to avoid seeing reality.
