Had an interesting experience last night. Felt strong sensations return to my penis. It actually wasn't a very comfortable feeling, but it felt extremely sensitive. I had to urinate several times that night. I tried to relax in bed, and then got an erection. Had an erection while I was awake, and then a very rigid one when I woke up that stayed with me for a bit while I was awake. I thought "great! I'm making huge progress really quickly" This was all with no PMO. I haven't orgasm-ed or even edged in 2 weeks. And I did not orgasm last night. I keep my hands away. But then today in late morning I felt absolutely awful. Felt severe withdrawal symptoms, and the craving to "binge" (I think). Had a headache and felt sick to my stomach for a few hours. For the most part it seems to have passed, but it seems like my excitement last night created a withdrawal response today. However, I did not relapse, and did not orgasm. It was a huge struggle though! but I did make through it. It almost feels like I relapsed without relapsing. Is that something anyone else has experienced. Thankfully I feel much better now and am still PMO-free. Man that wasn't fun!
