I've been using it with success. There are other members here with far more sober time than me who use RR's AVRT method. As Carl pointed out, it's a matter of commitment. With AVRT, you commit to quitting, once and for all, as in I" will never drink again, and I will never change my mind". You then use recognition of the addictive voice to keep that commitment.
I suggest reading and giving some deep thought to the material in the quick course on the RR website, and I also suggest reading and studying the book Rational Recovery; The New Cure for Substance Addiction. Cheap copies can be bought on half.com
And of course, participate on this sub-forum if you have questions or concerns.
Good luck.
