I'm using AVRT as well. I took the crash course. I just quit a little over a week ago, but considering I tried to quit a million times in the past 20 years and never made it more than a day or two, I think it's very effective.
This time using AVRT just feels so different. Every time I tried to quit in the past, I was really motivated and I really meant it, but I just didn't have the tools to make it stick.
I had a pretty rough withdrawal, and my AV chatters nonstop, but I'm actually having fun identifying it and just letting it whine and try to manipulate me. I've already been to a restaurant with friends (people and places) with no trouble at all. It's just so much annoying background chatter. I feel like a different person... me.
