I'm not saying that you can decide not to be addicted anymore, just that there has to be a point when you can let go of the whole thing - and move to better mental, emotional, physical and spiritual pastures. A hypothetical: an eighty year old who hasn't PMO'd for fifty years. You think the moment he no longer considers himself an addict he's running the risk of a reset? Fifty years in chat sessions, reaffirming his addiction in a group setting; always afraid he might relapse. To me, that attitude is the definition of an addictive mindset.
Isn't this whole thing about regaining your power? Signing up to a religious programme that tells you that you are weak and powerless in the face of your brain coding, popping pills to combat your anxiety - sure, it may work for a little while to take the edge off the worst of it, if say, you're coming off a really intense addiction / binge, but it's just scaffolding, right? It's gotta come down at some point!
In regard to the powerlessness comment, please look into Emotional Freedom Technique (EFT). It's a technique that makes use of pressure points in your body to release emotional load. You may be powerless in the face of your impulses if you try to white-knuckle them with sheer willpower, but there are ways to engage your body in a conversation about what you're craving - to add a voice of reason to the debate, and to greatly reduce the physical component of what you're going through. True story, I did an EFT session a couple of years ago that lasted one hour (took me about two hours in preparation) - that's three hours of my life. I wrote down all the beliefs I had about PMO, how I truly felt about it and how I felt about myself doing it, ideas like "I can never give this up" to "this is so silly - I don't even find these chicks attractive" to "I want a real girlfriend" and a whole lot more. I didn't use P for more than two months following this session; hardly even thought about it. The physical component had become so much less that the rest became a dawdle.
Yes, admittedly, I did eventually come back to it, but on a totally different level. Ever since that session, it has gone from a habit that I engaged in almost daily, and felt a tremendous amount of emotional intensity around, to a once a week, "meh - let's get this over with" type thing. Sure, it's still not okay, but it's a whole sight better than where it was at before - and that's just after one session.
What I'm saying is that there are ways to create a more permanent sort of healing. Find out about EFT and learn to engage your body in conversation.
