I quit smoking 10 years ago. I was stationed in Iceland and was just fed up with having to stand outside and fight the wind to light my smokes. I just threw my smokes away and gave up. The first few weeks were the hardest especially at work but what I found helped was to stay busy. Smoking was my boredom past time..so if I wasn't bored I wouldnt think about it. It worked. Cold Turkey is the way to go but it takes some serious willpower.
