I quit just after New Year and I haven't had one since.

It was easy for me, all I had to do was stop putting them in my mouth.

I found an article online that helped a lot, it is titled "Never Take Another Puff" by Joel Spitzer. I read it one night and quit the next day. Well worth a read.

Joel was one of the first to recognise smoking as an addiction when the medical establishment still classed it as a habit. In the PDF he explains the mechanisms that drive addiction and why patches and gum and all forms of of nicotine replacement hardly ever work.  Read it and then read it again each day for a few days after you quit and you'll have a good chance of kicking the habit.
