On the CD Susan puts you into a meditative state, taking you back to early childhood and through to to the time you started having negative thoughts about food.
All you have to do is relax and listen to the CD and Susan will do all the work for you. When you've found the root of your problem, Susan will press your 'delete' button.
This may all sound a little odd, and lots of us may not think we have these memories. If we do, it also seems a little to simple to suggest they can just be switched off. But, once you're hytpnotised, Susan's reckons it really is very straight forward.
