Hi, BackBeat, welcome to the secular side of SR. The crash course from the RR website is very good, and you can get your very own copy of the AVRT book, The New Cure for Substance Addiction, from a number of online sources, including Amazon, with used copies for cheap.
This thread is really a record of people's questions and answers as they worked through this mental exercise, got it, and then got on with life and their fine sober selfs. I read it eagerly when I found it, and it went a long ways to help with my understanding. With over 2500 posts, there is a lot of accumulated wisdom here.
Looking forward to your posts, BackBeat, glad you are here.
