As someone who's worked years to get his parents to stop smoking*, I can tell you it probably won't be easy even if you want to. I suggest getting someone who can and will embarrass you any time you touch one; it's a good motivator, haha. Aside from that, I have no advice as I've never touched a cigarette. That being said, I noticed everyone else was wishing good luck and I had neglected to do so; I apologize, and now here's a wish of good luck!

*It's worth noting that my parents, as far as I can remember, have never been heavy smokers (1 or 2 a day). Also, they have always been very good about taking it out of the house - which is nice.
