there are a lot of charlatins out there, just as there are some excellent hypnotherapists. unfortunately, few, if any, municipalities regulate this form of therapy. i have known a few licensed therapists who occationally used hypnosis in their practice. however, i would not use a piece of paper (degree, license, etc) be my sole criteria in selecting a hypnotherapist. remember that even freud, who more-or-less pioneered this specialty, gave up using hypnosis as a theraputic tool fairly early in his reserch.
i have also known unlicensed practicioners who were very good - and more who were as close to quacks as i would ever want to associate.
about 20 yrs ago my wife and i went to a non-licensed hypnotherapist to help us give up smoking. he man was very capable, well educated, and well trained. after a single session, my wife was able to do without a cigarette for about two weeks. i lasted about two weeks and two days. i had four VERAY large contracts that fell through at the same time. if you lost over a million dollars, i expect the stress would drive you back to cigs, too.
hope this helps. let us kniow how it goes, whatever you decide to do.
That light at the end of he tunnel? It's an on-coming train.
