Two thing I did helped me quit after 11 years -- one was to leverage being sick, then sleeping a lot - basically sleeping through the hardest part of the withdrawal. The other was to embrace all the things I did when I smoked - for instance, I still took my smoke breaks at work. Afterwork I used to go to a coffee shop for some java and for a couple of cigarettes to unwind and think about my day. So I continued to do that. At home I'd smoke on my landing or patio (not inside), so every time I wanted a cigarette I'd go out to where I'd have it. Sometimes I would even mimic smoking a cigarette, bringing my hand to my mouth and inhaling deeply. I found I used my smoking time as thinking time, so I'd continue to do that as well. It sounds weird, but I think what helped was that I was giving up only 1 habit (actual smoking), but not all the other habits that were integrated with my smoking. I was remaking one small aspect of my life, not trying to recreate an entire lifestyle.
I don't have any words from the Buddha, but there are teachings that about how heaven and hell are just creations of our own mind. I'd suggest not looking at quitting as a "hell" that you must battle through. Embrace each moment and each craving as a beautiful feeling in itself. Also, I know when it comes to lust, I've heard suggestions about thinking of the other person as a rotting corpse, etc. to make the desirable thing undesirable. You could do that with cigarettes. Imagine them as whatever turns your stomach.
I know it's not easy, and the hardest part is that cigarettes, or the nicotine, or the addiction itself "talks" to you. "Yes, I'm bad for you, but one more won't hurt. Start tomorrow. Etc." However you go about it, Good luck! And let us know how it goes.
