Hi, Jaz, it sounds like you have decided to get serious about this now, and that is a very good sign. While you are waiting for the AVRT book to be delivered, you can look at the condensed version of the book called The Crash Course that is available for free on the Rational Recovery website. It may be just what you are looking for.
If you have any questions or would like to introduce yourself to SR's ' AVRT support group', make a post on the
Secular Connections forum. That's where AVRT and the other alternatives to 12 Step recovery are discussed. We will be most delighted to see you there.
