About 3 weeks ago, I was running (reasonably fast, been running for years and even racing so I'm fit ) and I got a really bad headache. I was going too fast. At this time I was on about 30 days streak. First time, many years. Anyway, doc said it was an exercise headache. Since then, I've had slight headaches, and just got a slight cold. Given I have never had a headache from exercise, is it possible this is related to my NoFap? Finally, I'm thankful for nofap.
Could be, I was running fast after a race. I think it's a combo of desk setup and exercise strain. I did read NoFap can cause headaches.
You could be doing too much to avoid fapping. You need to learn how to be still and fight urges not be in constant motion to avoid or deal with them.
