Did anyone smoke after the supposed quit date?

I haven't taken Chantix myself but the link below has reviews made by people who have used it. You may find it useful.

The packet says to stop between day 8 and 14, preferably day 8. I am on day 17. smoked a few cigarettes in the evening of day 15 and a couple leftover butts left in the ashtray last night. You kinda just have to say okay this is my last one. Chantix doesn't kill the cravings completely, hence the weaknesses of days 15 and 16 above. But I find that instead of my head screaming at me that I want to smoke, its just chatter that I can distract myself from. I personally am looking forward to the vivid dreams and don't have restless sleep. Part of the restless sleep also may be your body wanting the nicotine as its not out of your system yet. Mine either and I can't wait to sleep through the night. Good luck to us both.
