Chantix
"I'm a 62 year old male and have been smoking since I was 19. For the past 20  years pack a day. Tried to quit before, cold turkey. Tried the patch 3x... Wellbutrin last time. PCP had prescribed Chantix before and I chickened out on using it.  

Am now 8 weeks on Chantix. Last smoke was at the end of the first week. Have not smoked since Quit Day... and haven't had an awful lot of urge to smoke either.  I'll sometimes now forget to take my pill until 9-10am when I remember it ... same in the evening... which means if I wake up at 2am.  I am AWAKE.  Bummer.  So definitely need to remember the evening pill at 6pm ... which is when I get my daily phone call from Get Quit.

Just picked up my 3rd month of Chantix."
