Which is affected by the time it takes to be successful in stopping porn viewing ?

I have a question, what factors affect the success of getting out of PORN. Because by default it is about 90 days, but this time is supposedly variable and I have a question what it depends on.

 

And is there a document on the Internet about the exit from pornograffi similar to this https://benzo.org.uk/polman/bzcha03.htm

 

It can be in any language, preferably Polish.
