Woah headaches.

Ok, so I started no PMO a month and a half ago (not really counting, just going with it). I have been in a flat line (emotionally and physically) for most of it, with the exception of the first 2 weeks. I have been having spouts of headaches, and laziness in general. I haven't necessarily attributed this to PMO or anything, but last night was odd. I was getting intamate with someone (just deep making out, rubbing, and cuddling), and then as their hands came to touch my boner I felt a headache coming on. It was odd. The longer we went the more I felt this slight headache in my head even more. I know this isn't exact science, but it's odd to me because this has been happening a lot lately when I have random thoughts of PMO throughout the day. My questions to you guys are,do you think it's possible to feel your brain rewiring? Does this seem like a side effect of withdrawal or something? I also might add that I rarely get headaches, but the have been way more frequent sense quitting PMO.
