I fully agree. One should never feel guilty or ashamed for it. Porn is a serious drug and an withdrawl from it should be treated as such.
Of course.
The mentioned timeframe was supposed to be an example, of how devastating it is to snap back into these habbits, if one heals energysystem/brain but not the rootcause. = Trauma that leads to low-self esteem.
Repeating a cycle of being successfull for some time (self esteem 
) and then snapping back into unhealthy habbits (self esteem 
) just wrecks further havoc on the persons mental and emotional state.
You end up feeling even more devastated and hating yourself even more bc you´ve been clean, everything felt like it´s going well and boom suddenly you´re back at it.
Maybe I´ve worded it poorly, I am not getting much sleep lately.
I don´t recommend cold-turkey, as your last saved hyper-stimuli is the fetish you are trying to leave behind.
So I see 2 possibilities:
Slowly reduce the intensity of the genre. Try to get used to less hardcore stuff, little by little. At some point you can step down to a less extreme genre and so on.
and/or
Switch to just audios, then to texts. Reduce the amount of stimulating channels
Then of course Cord Cutting, Soul Restoration, Brain fields etc.:
Also try to reach out to your Higher Self, Angels and Aliens for help.
