Isn't this the triple A approach? I've come across it on the internet. They pride themselves on being hardcore, no-nonsense, literalist. They make reference to the 75% recovery rates of the programme of the 40s rather than the single figures rates which are touted around now.
It sounds fascinating. Having been a product of the "drag it out as long as possible school" particularly! My only problem with it, when I've listened to the tapes of their practitioners and read their approach, is that they don't have what I want.
