I know that some hypnotherapists practice CBT techniques and that way you usually go to their home or studio and its much more personal and I would imagine much more effective, why dont you do a search on the web and see what they say. Also a hypnotherapist would be able to reprogramme your thoughts with regards to food also.
If you are nervous of hypnotherpay or have never experienced it, I have some personal experience and think it was the best money I ever spent, 50 quid and I had a four hour session and didnt need another and I am happy to speak to you in a PM if you would like to know more of how it affected me.
I am sure there will be lots of info out there and I am sure I have seen PMK do lots of CBT techniques on some of his programs and I trust him!
