I've been where you are, I just gave up on quitting.
In response to your question, I did try hypnosis. In fact, I forked over the extra $200 for a private session. Lets just say, I didn't make it out of the office building before lighting up
I've talked with lots of people who quit smoking. The vast majority have just quit cold turkey. I understand that it isn't the suggested way to quit, but hey if it works. When my Mom died Sept 2001 of lung cancer, I still didn't quit. I even held her hand as she was dying, I still didn't quit. I know I should for all the right reasons, I just haven't put my mind to it yet.
Anyhoo...lotsa luck on your journey. Keep us updated!
