Today, after 10 days of Nofap, I relapsed when I accidently watched a porn vid on my brother's phone. The interesting thing is that I was very positive since day 5 but after I relapsed, all of it went down the drain. I immediately started feeling depressed and drained. But, the thing is I found a way to get out of that. And that was connecting with people. I went to a neighbour's and interacted for like 15 minutes. And guess what? My energy came back on. Though not as strong as before but I feel it. Its not that awesome but its there. So if you have relapsed and you feel shitty, go out and meet people. Its an effective way and has worked for me.
No, I am sorry I didn't have a headache. But it was one of the rarest times when I felt depressed and need for help...
