I know of many folks who have been hypnotized for smoking cessation and weight loss, all with varying degrees of success.
I was hypnotized while undergoing therapy with a trained psychiatrist to help me get to some stuff that was buried really deep. Did it cure my anxiety/panic? No. Did the insights I obtained and a LOT more therapy cure my anxiety/panic? For the most part, yes.
Do I think it can cure you without having to do any other "work?" No.
Just my opinion.
And I also advise, if you want to try the hypnosis route, that you go with a psychiatrist trained in hypnosis.
