I quit cold turkey it was the single hardest thing I've done. I have been begging my wife to quit, she will and then she will relapse and start smoking again. It is a matter of will power if you truely want to quit you will. Like Scruit said take a look at your loved ones and think about them. Every time you smoke you are taking time away that you and your loved ones could spend together. Be strong man you will get through it. The longer you don't smoke the easier it is not to. I started smoking when I was 13yrs old I decided to quit when I was up to 2 1/2 packs a day at age 27. I'm 34 and managed to not smoke anymore. I wish you luck with quiting.
