Without knowing it I used an AVRT-like mindset to quit smoking many years ago...if you truly make a decision to quit it is wholly within yourself to make that happen...to me it is that simple! Note I didn't say easy.
The crash course made perfect sense to me but the book itself will provide you with further insights.
SR was most valuable to me in the beginning because it took away the "specialness" of my struggle...I could recognize my internal AV because I saw the same thoughts expressed here every day.
I'd say good luck but with AVRT luck has nothing to do with it!
