The one big challenge I've had with AVRT in the past is since I'm primarily a weekend drinker, my Beast is very quiet most of the week. It was the same when I smoked cigarettes; I could go without smoking all week and then Friday night, as soon as I left work I was dying for a cigarette.
Because of this, I seem to not get the practice in until the Beast and his AV are hitting me full force. Yesterday and today I feel 100% confident in my Big Plan, but come Thursday (I'm off Friday, making it a weekend night), I fear the attack - but I guess that's just the Beast speaking.
BTW, I've got a call with Jack Trimpey today to discuss the class. I'll let you know how it goes.
In the meanwhile, I've been listening to AVRT Live during my commute, and re-reading The Cure and this thread from the beginning.
