Day 2

I would say about 3-4 weeks until its noticeably easier, and depends on if you are still or previously watched porn. If you are still watching porn, very difficult. IMO when porn was involved if you can avoid porn you will likely flat-line for a period at about 1-2 weeks in (loss of drive). With MO alone, your porn is in your head and the change is more linear.

I firmly believe that going cold turkey is pretty rare. You have to experience going for longer and longer periods, then feel like what it feels to relapse again to compare. I also believe that most people can do anything in moderation, however if the damage is severe enough from too much PMO/MO eventually getting to a 90 day streak will do you very well in establishing the benefits for you. The change that makes it easier is not about resistance, but is more about changing your mindset (redirecting your mind to something else by changing habits).

Something I have yet to see mentioned here directly in this forum is that people, such as myself, sometimes did not have shame in PMO initially, UNTIL we came to believe that its negatively affecting our lives. Once you truly feel that PMO/MO is a bad thing with any regularity for yourself, it will become easier to go longer. In my case the sense of shame (sense I failed myself) increased dramatically as my mindset changed. Don't exaggerate in your mind how bad it is to reset your streak, its more about the long view change your targeting.
