Prior to nofap I was very clever, articulate, and was able to concentrate without spacing out. I'm on day 65 of nofap. For the past few weeks, it's been hard for me to think clearly, verbally express myself, and concentrate on things without zoning out. Like, my mind feels foggy as I'm typing this and it's annoying. I just feel so stupid and dumb and it's bad due to the fact I have to take a test next week. What is going on?
Kicking an addiction generates a lot of physical and psychological stress. A little mental fatigue is to be expected. The reboot might be draining you without you even realising it. Don't be discouraged and stay vigilant!
