Hi, Backbeat.
When I first came across AVRT, I was also struck by a sense of instant familiarity, of having been doing a lot of the things already, even if I hadn't clearly articulated them. Not surprising I guess, since Trimpey based RR on the experiences of people who had recovered on their own.
I also see a lot of parallels to Buddhist thinking. I'm a huge fan of the old Stoics, too, and see some striking overlap there as well. Actually I think AVRT is quite complementary to most philosophical and religious perspectives; it just doesn't define addiction as a spiritual problem, nor does it rely on a spiritual solution.
