Simply stated---usually the habitual development of these pathways create compulsion and the unconscious triggers need to be controlled and then neutralized. Early traumas work needs to be done, with practical body based methods to quell the urge and self imposed penalties to allow for falling but pay a price. Cognitive vision of why its not good for the client and designing a picture of life without it that is compelling, possible, and desirable. I have only seen that Matrix work fully does the job and also quickly. Of course, you need will or the way to build the will first  The goal with Matrix work is allways the same—rewrite the past to transform the future---this means actually transforming the compelling urge. See document (below) from the founder of Matrix to explain theory.
