Once when I was going to be staying with my mother for a week, I had to quit smoking for that time (she doesn't know I smoke - dad died of lung cancer = very sensitive topic in our family). By chance I picked up Paul McKenna's book on how to quit smoking with a hypnosis cd with it at the airport. I skimmed through the book, some of the techniques seemed really good, but I didn't try them as I didn't want to quit forever. I just listened to the hypnosis cd at night and amazingly, the next few days I had no cravings at all! I took up smoking again after that week though.
Hypnosis is a bit hit and miss though. It helps many people, but for others it doesn't. As my therapist explained it, hypnosis is excellent for things that are pure habit, but sometimes there are strong psychological factors behind smoking too. But I think hypnosis is a good addition to other techniques. At the very least, it'll help relax you. I've temporarily quit a few times using nicotine gum too (same situation as above, visiting family). Nicotine gum is very dependent on the brand, I find. Niquitin is my favourite, the rest of them don't really do it for me.
I actually do plan to quit this year. I've always said that smoking is one of the last of my vices that I'll work on, and I don't feel quite ready to give it up until I've sorted out a few other things in my life. But I'm getting there, so perhaps I'll be ready by the next time I go and visit my mother abroad (in March/April). It's convenient to have a change of scenery and a break from new habits while you quit. And like mariacallas said, you have to have that strong desire to quit, and I haven't had it before. Once I quit for real I plan on using nicotine gum to smooth me over the first week or so, listen to the hypnosis CD every night, and use EFT to eliminate psychological factors. I think maintaining a healthy diet does good too, to balance the energy levels and emotions, perhaps supplements for anxiety if there is any (theanine is the only one I've found that works, but you have to take way more than the recommended dose).
All in time
Lately I've taken up a great liking to
snus, which makes me smoke less, but apparently it's more difficult to quit due to higher nicotine levels. 8( But, as I said, all in time.
