When im relapsing, this same thing tends to happen..

excitement?

 

It sounds almost too obvious, but likely you get into state of partial undress when relapsing along with reduced blood flow to your non-genital extremities, which in the northern hemisphere this time of year means you are going to be cold. Keep that fly zipped and all your problems go away

 

That makes sense. I always thought it was just me trembling with excitement or something. XD This happens to me pretty much every time I relapse and I absolutely hate it.

 

I experience this too, I think it is something to do with excitement, or perhaps even anxiety. I actually experienced the same kind of shakes when I was about to have my first kiss as a teenager. It hasn't happened every time i've relapsed but it definitely did last time after a 3/4 month streak.

 

I've experienced something similar (without the cold and shivery bit). I think it's the conflict in your brain. Part of your mind wants you to relapse, another part of your mind wants to do nofap, and is nervous because you're about to ruin your streak if you relapse. I'm fairly confident it's this, because when I was watching P before I started trying to quit, I wouldn't feel any of those symptoms.

The solution has already been proposed by Redominion. Stay away from porn.
