In my signature there is a link for stuck in relapse. at the end of the post there is a video that explains relapse. You might look at my plan too. Just adjust to your background.
Dude I have been trying for the last 6 years and I haven't gone 2 months PMO free yet. Don't be afraid of failing. It's all about learning from your relapses and discovering new techniques and following them strictly until you get use to them and one day you will come out of this hell. Good luck!
