ujyalo,

I can relate. I am experiencing the same. I found bittertruth's post spot on. I researched about this few months ago when I start to get worried about myself. All of symptom that bittertruth mentions, except morphing, applies to me. I tried to quit porn. I was determined. But I lasted only two days. I really want to quit porn. I know it's killing me.

I came across this video(Tedx Talk) that you might find helpful.
