My husband smokes, sounds a lot like you, says he enjoys it also and does not believe he would be able to quit. He did quit once, for a couple weeks, using an electronic/computer thing where he smoked normally for a week while it recorded his pattern and then it started telling him when he was allowed to smoke, gradually weaning him off.

He can afford to smoke (although I wish he would use the money for something else). If you cannot afford it, I would not buy cigarettes anymore; I did that when I wanted to stop eating fast food; just quit going completely.

I would treat cravings and desires as an "illness" and deal with them as I would any other illness or physical problem; you can't get over a cold for at least a week, no matter what, or stop throwing up if you have the stomach flu, etc. Treat them as symptoms of an illness and be good to yourself but don't give them "control" over you. You are not your cough when you have a cold; why be your cough when you smoke, or your cravings. Make them symptoms of something larger instead of keeping them personal. It is not a failing in you to have them, just to give in to them!
