Allen Carr is an American author who helped over 50 million people quit various addictions most notably smoking.
Recently I read a slightly modified version on P although it was not written by him it was and still is profoundly helpful. 
you can find his book on amazon It's not very expensive and with some creativity i think you can see how it helps PMO not just smoking. 

here's an example of what I mean:
"The whole business of smoking (porn) is like forcing yourself to wear tight shoes just to get the pleasure of taking them off."- Allen Carr

if you don't want to buy it or if you want the version that helped me tremendously you can reach out: thegravegye@gmail.com

Easy peasy book. Link is in my signature. An interesting read, though it seems like it doesn't work for most folks.

I think the "find the fox" technique in F2F is a variant of the "addictive voice recognition" technique which is a repackaging of the easy peasy method.
