Suprisingly yes. I and my partner quit on August 15th and have not relapsed once. It has not been easy at all. There were times when I literally wanted to either kill him and then smoke, or smoke and then kill him LoL - I even lost my job a week ago and STILL haven't smoked!
Chantrix works wonders. It makes you forget to crave nicotine. However, it does make you feel a little like you are losing your mind too - and after about 2 weeks I quit taking it. The urge to smoke did not intensify after I quit taking Chantrix, and it was pretty much then, that I knew I was done.
Nearly 3 months free now, and I know I won't smoke anymore - being anywhere near someone who is doing it is rather rare, and when it does happen, it totally grosses me out.
We had some friends over last night who wanted to smoke a joint. I've never been opposed to that sort of thing - so I ran about trying to find a lighter and an ash tray. The funny part was I couldn't find either!! It was quite a realization! Felt very very good.
