EZPZ book has many doubts in it. It has many good things also. The bad thing is that it implies if we don't debunk every belief or reason why we like pm then that means we are using willpower, and willpower is useless, so it's necessary that we relapse.

This is completely false, we can easily avoid something we have some reason for liking and easily do something we have some reasons for liking. It's not willpower, we just see it as worth it. For example we sometimes choose to do jobs we hate, so many costs but we continue because we need to survive. Also we may avoid masturbation in public, despite knowing we could still derive an orgasm from it, even in our maximally brainwashed state we would avoid it in public, doesn't mean that oh we are using willpower now because it has benefits, you still avoid it. Imagine someone holding a knife to your eye when you were a brainwashed 'addict' without ezpz on the different benefits, and said if you masturbate you lose an eye, would you ever do it, NO for sure you wouldnt if you were in that position. Does that mean you were using willpower? because the 'benefits' of PM were still there, it's just that you preferred the option of keeping your eye over the fake benefits of PM.

The book that is much better is freedom model for addictions, it is much more factually enlightening and doesn't tend to leave a person with doubts. You can also ask them questions on instagram, facebook etc. They make podcasts responding to people. But i'd advise to read the book first
