I've been doing NoFap for 20 months now. Had a few sporadic relapses here and there, but nothing that I would consider too severe. I've heard stories about people who relapse and go on edging binges three times a day for a week, but I never did anything like that; my relapses were always pretty tame compared to some that I've read about around here. About a week ago, I felt like I had a major breakthrough. I was waking up in good moods, my attention span was great, hardly any brain fog, lots of energy to do things, and generally feeling more optimistic than usual. That only lasted for about five days before the pendulum swung the other way and everything came crashing down. Now I'm feeling a lot of sadness, sorrow, anxiety, and I'm having a lot of random flashbacks of old memories for some reason. (I don't mean porn flashbacks; I mean just general life memories.) These flashbacks come out of nowhere and are pretty vivid. When I have them, I feel a lot of old emotions surfacing that I haven't felt in years. It's almost like certain parts of my brain are gradually coming back online. Aside from that, I noticed about a week ago that my fetishes are practically nonexistent now; it's gotten to the point where I don't even think about them or care about them anymore. I'm also experiencing a lot of the physical flu-like withdrawal symptoms that I had when I first started NoFap: headaches, sinus pain, body pains, chills, and a general yucky malaise that's hard to put into words. Are these all signs that my brain is going through a phase of intense rewiring and healing? I have this weird feeling of emotional rawness and vulnerability that I've never experienced before during my reboot. I'm thinking that maybe the really big changes are starting now after 20 months. Is it normal to be on this roller coaster of sharp ups and downs when major changes are occurring?
