What Brain and Arbor describe is really the essence of what Trimpey coined as the Big Plan. He based his techniques on strategies the self recovered used. So it makes sense that people read AVRT and say "oh... that's how I did it." It's been going on for hundreds of years, people quitting in this manner. It's only in more recent times that popular thought tells people that quitting this way is not possible. That's it's too simple. That's hogwash. People have been ending their suffering with addictions in similar fashion for eons.
