Also, forgot to mention, a lot of it is aversion therapy (Alan Carr) like collecting all your cigarette butts from the day before in a ziplock bag then smelling it first thing in the a.m. before smoking... (mmmm.... smelled delicious to me, LOL) with some pretty strong motivational enhancement. They aren't the best techniques for behavior change, but they aren't totally ineffective either. What I found gimmicky was his writing style, not necessarily his techniques.
POSITIVE reinforcement is a much more powerful tool, which (IMHO) is why vaping works. You do get the positive reinforcement of nicotine, but additionally flavors, the ability to select equipment, the pleasure in learning new things (natural human tendency, IMO), and the enjoyment of success. Positive reinforcement is a much more powerful tool for ongoing behavior change, which is why vaping is successful for many folks, encouragement, education, and support are also powerful methods of positive reinforcement which is why ECF can be such a helpful site, and that's why I love vaping! I've gotten to the point where I can be self-reinforcing through cravings, oral surgery, and everything else. Vaping kind of builds on itself, once people start achieving success, again IMO.
Okay, climbing off the Behavioral chain analysis of cold turkey versus vaping, starting.... Now.
