AVRT is about self recovery, not unecessary dependency. I believe there are some old posts discussing the fact that dependency is the original problem and that more dependency won't solve it. The AVRT threads are a wonderful resource and I personally find these discussions interesting. The book is important, and other related materials can most certainly be helpful...but the bottom line is- the onus is on the individual to take the information and use it to quit. Anyone is fully capable of recovering. Believe that.
