It's been 11 years since I've #smoked a #cigarette; #Chantix worked great for me.
The 2-3 times I tried to #smoke in the first year, I took one drag and coughed so hard it kinda hurt.
Within 3 days of starting on Chantix, I stopped getting that sweet #nicotine #buzz and got only smoke, which was pointless to me so I stopped a few days before the suggested final cutoff.
For 2-3 years I got occasional cravings, usually when watching movies or tv, and since then they've faded to almost nothing.
