x3 on Chantix.. I smoked for 15 years... have tried to quit on various methods, wellbutrin/zyban, the patch, the gum, cold turkey, etc.. all worked in their various degrees, but never fully. Did Chantix in the beginning of this year.. as mentioned above, it just makes smoking not enjoyable... you basically just get a shitty taste in your mouth and an inconvience to smoke the cigarette.. it took me about 2 weeks from the time I first started taking it until I had my absolute last cigarette.. I continued on the pills for another 2 weeks or so, then stopped taking them.
I haven't had a cigarette in 9 months now, and I honestly don't miss it.
Also, some insurance plans cover Chantix, most do not though.. but the 130/mo is nothing compared to cigarettes... I have a 'quit calculator' i downloaded off the net, and here is how much ive saved with life&$$ [3/4 of a pack a day, ~$6.50/pack in Jersey];
Smoke free for 8 Months, 24 Days, 23 Hours and 38 Minutes, while extending my life expectancy 13 Days and 22 Hours, by avoiding the use of 4020 cigarettes that would have cost me $1,320.92.
