Relapsed after 52 days - how bad is it?

"Only" M'ing is called edging, and it's still very problematic, as you experienced for yourself that sometimes it'll cause you to actually O, and this is besides the other problems of M.
As for your question: That's really up to you. Time will tell whether or not you can hold on to your current commitment for 90+ days or relapse again.
On a more positive note, 52 days is a very impressive streak, and should not be taken lightly - I'm sure your willpower was very greatly strengthened these past couple of months, and that should help you restart.
I suggest you go and retrace your steps: Why were you depressed? What can be done about that? Why didn't you wake up and immediately jump out of bed? Find solutions for that, get a battle plan ready, make sure you do your best.
Good luck!

 

Well, 90 days is the minimum. And you decide how you feel after 90 days, whether or not you want/need to continue. But you generally speaking, you don't need to add 52 days to the 90. It doesn't work that way.

 

Complete Reboot would take years till you have no memory of all the stuff you have been watching over years in my opinion ..its same if you can't remember a movie you watched 5 years ago and watch it again and ask yourself in the middle of it if you know the movie you know physically i think one year atleast to go through all seasons and temperature changes

 

I am on day 27 later on today and my memories are similar to a youtube video "Acetone destroys your lego"

So I can still remember pretty everything but it is losing its sharp edges and shapes so the memory of porn pics and videos are a bit distorted and not so saturated. So "noPMO" destroys your porn memory.
