My OH has been hypnotised 3 times to stop smoking, the first 2 lasted about 6-12 months each time, the last time however used hypnosis and NLP (neuro Linguistic Programming), this was about 3 years ago, and he's not desired a ciggie since. He was so impressed with it, he's now undertaken the training to become an NLP practitioner himself. He wants to specialise in weight loss, but it can work for a wide range of "issues", he has a client coming in who wants to regain some enthusiasm for exercise in general.
Like anything, success depends on the willingness of the person undergoing it to actually want to change the behaviour. If for example a person wants to stop smoking because their OH doesn't like it, then it probably won't be as successful as someone who truly wants to stop for themselves.
If you have any questions PM me and I'll ask "him indoors".
