I think it's interesting that really the crash course is all that's required but that there's a book there too. It's a dichotomy really but again, if you question too hard the house of cards can come falling down. My desire is to think about drinking as I now do about smoking (and drugging, I didn't go into that one but all of that is behind me too). AVRT is an awesome tool so long as one does not place a crowbar against it and push too hard. And if I can see that the idea of placing a crowbar against it is my AV then all is good. x
