Like you, I'm an all or nothing person. I never tried hypnosis, but one of my good friends did. She had many sessions, one-on-one, with a licensed psychologist/psychiatrist(?). She felt it did her a lot of good, but I didn't notice that she lost much weight. I think she just needed someone to talk to. My in-laws also tried one of those mass hynosis sessions to quit smoking. No luck either.
I do have a suggestion that may help, though. Until recently, I was on Weight Watchers. With that plan, you can eat tons and tons of food and still lose weight. Most of it has to be "good" food, but there are also lots of "legal" snacks, like fudge bars, cheesecake, chocolate mousse, etc. Of course, if you're trying to get rid of sweets for reasons other than losing weight, this wouldn't do you much good. Still, it really helped me to be able to eat such a variety of food and even include sweet treats on a daily basis. This plan worked beautifully for me, even though I'm diabetic. I'm not even taking medicine anymore. Because we're both all-or-nothings, maybe it will work for you, too. It's a thought, anyway. As Cathe says, "take it or leave it."
Best wishes
