i used
www.chantix.com after a week or so I had no sensation to smoke. that was 2 1/2 years ago. i was smoking anywhere from 2-3 packs a day for about 7-8 years. i never thought i would be able to quit but now i look back and see how nasty it is.
some people bitch about the nightmares while taking chantix. this was true for me but 1-2 weeks of nightmares beats the shit out of lung cancer
also chantix is one of the few methods that lets you smoke while taking it. some of these patches and stuff want you to not smoke while using them. does not make a lot of sense to me.
and yes you have to WANT to quit or nothing will work
