I have never met -anybody- who has quit smoking as a result of
hypnotism.
On the other hand, I have met many, many people who, like me, have
wasted money in the hopes that it would work.
There are no magic pills, potions, patches or tricks that will make
you stop.
What _may_ be helpful would be ongoing counseling during the initial
phases of your quit, and that could include some sort of
hypnotherapy.
I don't think that's what you're looking for, though. I think you'd
like it if you could throw $100 at somebody, spend an hour in their
office and walk out a non-smoker. Sadly, that ain't the kind of thing
that happens.
I hope you find great success in your upcoming quit.
Mike
