I quit with Chantix. I took Chantix 3 weeks before I layed my cigs down. I quit smoking April 12th. On April 29th, I stopped Chantix. I'm still not smoking. I don't think I could have quit without it. I quit once before cold turkey and made it 6 weeks. I feel Chantix gave me a chance.
I'm sure it's not for everyone and some will have side effects. I had some nausea in the evenings with my evening pill, but not in the morning with the morning pill...strange huh. I had vivid dreams but no nightmares. I was not depressed or suicidal. I know drugs affect everyone differently, but I have nothing but good to say about Chantix.
