smoking cessation
"I'm stopping smoking for years now, tried everything. And I mean EVERYTHING, and repeatedly. I thought this is not going to happen, ever. Then I started Chantix and it is over 4 months now that I did not have a single cigarette. Even though these urges are still there, it definitely takes the edge of it, and makes quitting manageable. 
True - you also have to be ready. I just hated it lately, the smell, the whole thing - but was unable to say "no" to it. It is disgusting, nasty habit, and I'm so glad that I did it. I'll NEVER pick up a cigarette again, after all that I have to go through to finally make it. Good luck folks - Chantix works! I didn't even have to finish it all - stopped taking it about half way through the second box."
