It's hard to know for sure. There isn't a magic number that after X days you are "normal" again (whatever that means).
Your brain has gotten wired to equate porn with a big dopamine hit. This wiring will always be there to some degree but the less you use it, the weaker is gets.
I think a better way to measure progress is to look at your whole life. If things are getting better abd you're finding other activities to fill the void that porn did then that's good. If you're feeling more and tackling problems in your life, that's good. If you're still struggling with facing up to things abs taking charge of the life you want, that's less good.
It is all a process and gradual steps.
How do you feel? How do you think your recovery is going and why?
