I've known a few people who have seen hypnotists for help with things like quitting smoking. It's been met with mixed results. I wouldn't feel very comfortable being put into a trance and surrendering control to a stranger, but maybe I put too much stock in their skills. I also feel like their craft is a bit on the cusp of being questionable. Not that I think hypnotism doesn't work, I'd be more worried the hypnotist would implant the notion in my mind that I need to return to keep seeing them to get over my problem. I could never afford that.
