I have been wondering something; can hypnosis help me with my OCD problem? I am not saying that I will quit on my medication therapy but I am willing to try some additional, perhaps a bit different approach to my problem. And I admit that I have a problem and that I am willing to solve it.
I think I have heard that hypnosis might have a lot of success in dealing with disorders like OCD and other, similar ones. So, I think you should just inform your therapist about this different method you are willing to try and then try it! It really cannot harm you and you just might be near the solution for your OCD.
