This is why I loved Allan Carr's book, the easyway to quit smoking. It's been in print for decades and still getting 5 stars.
Because he DOESN'T use any of the scare tactics or graphic horror stories, he gently uses very subtle behavioral shifts and......they work. Read it while continuing to smoke, etc.
when you are done reading it you will have gained a tremendous amount of insight......into YOURSELF.
It works. That's all I gotta say, and I rarely see anyone suggesting reading material here, just buy buy buy more stuff, but you have to have OTHER TOOLS to quit an addiction. And this is one of them to add to your arsenal (and I bring it up not often enough.)
PS and no bash on Dan..the gorey stuff does work on some people, it's just another "route" to change things inside your mind/head. It's all good
