I quit smoking listening to the audiobook "The Easy Way To Quit Smoking" by Alan Carr. ?
Someone created a hackbook and now an audiobook of the No PMO version of it called "The Easypeasy Way To Quit Porn" ?
It is extremely well written as it it geared towards quitting porn using the same context that was used in the original book.
This can be an extremely great tool for everyone. I'm on chapter 22 of 30some and I wish the book would not end. It's definitely going to help!
