A good friend of mine who smoked for over 30 years quit recently with the help of Chantix, a prescription medicine. I was quite impressed with with her 180 and decided to ask my doctor for a prescription also.
I didn't have it filled right away. When I finally did the instructions were to take a pill in the morning and another pill in the afternoon. At first I didn't notice any change at all. Around the fourth day I was drastically cutting down on my smokes without any effort; they just weren't on my mind. The recommendation was to quit on day 8 but I was still having a few smokes.
I told this to my friend who recommended the Chantix in the first place. She said she also didn't quit on day 8. She said "I let the date pick me." Genius! I felt like a failure before she said that! Before I knew it, day 12 picked me. It was at the end of the day when I realized I hadn't had a smoke all day and didn't even realize it until bedtime. A miracle!
I continued taking the pills with the only side effect being some really whacky, crazy dreams. But I could deal with that. I planned on taking the Chantix for two months but forgot the pills a few days in a row after 6 weeks. So I decided to stop at that point and if I needed it again I still had some I could take. But it's been two weeks since then and I'm not even tempted.
I do have to admit that I fell off the Chantix wagon twice. I bummed a cigarette off someone and it turned out to be a Virginia Slim Ultra Light (hardly a cigarette for a Marlboro woman) and I coughed and hacked on my first drag! The second incident was nearly the same so when the old "triggers" (for me they were driving the car, long telephone conversations, watching tv in the evening, etc.) I just reminded myself of that hacking and that unpleasant shock when I thought it was going to be so good. And to be honest, those triggers (car, telephone, etc.) rarely triggered the urge in the first place.
My doctor actually did a little happy dance when I told her I didn't smoke anymore.

People have asked if it's okay to light up around me and I don't hesitate to say, "go ahead, it doesn't bother me at all!" I never could have imagined this a year ago! Never!
Since I started back to work after a six week break I've told me co-workers about it. Many of them have family, friends or neighbors that have recently had success with it also. Two of my relatives are going to try it soon and I really wish for them the same success I've had. There really is no up-side to smoking.
I thought I'd share my story here. I'm not trying to get down on the smokers...I've been there. I just want to say that it wouldn't hurt to give it a try. You might be surprised. Best wishes.
