I used Zyban pills when I quit. That was almost 10 years ago so I'm not sure if they're still available. Also, I found someone at work who wanted to quit too. We bet each other that the first person to smoke had to pay the other $500. I can't afford that kind of $ so that gave me good excuse not to smoke. Stay out of smoking situations for a while too. If you always smoke when you drink alcohol, try not to drink for a while. It's not going to hurt you if you don't drink fir a few weeks. Good luck! It can be done and if you want it bad enough you'll succeed.
I tried so many times with out success. Then I tried e-cigs. I used them for about 3 1/2 . That gave me what I needed to stop and not give in to the cravings. It was still very hard but i was able to do it.. I've been a non smoker for almost a year!!!!
