Spunkie, both my husband and I are Chantix quitters. He has stopped after 11 weeks (he was on one-per-day for about a week) and I'm doing 1 a day (I'm at 9 weeks). I have noticed we're both a little grumpier, and we're blaming the meds. Last weekend we both were out of sorts and it finally blew up over "how to properly clean the grill top." Sheesh....LOL... We called a truce, and have been getting along fine ever since. But it could be the heat too, or the realization that this quitting is a long-term thing. The excitement of being a new quitter is wearing off and now we're slogging along, day by day. Still not smoking, but we do talk about it. Still not smoking, but we think about it. Feeling great about not smoking, but we "miss" it. (Not really, but you know what I mean.) Some friends of ours used Chantix to quit earlier this year, and I remember them saying they were at each other's throats even after 10 weeks. At the time I wrote it off to their marriage chemistry (they're both a little hot-headed to begin with), but now I understand how that could have happened. BTW, they're still married, and they're still quit! I'm going to finish my Chantix packet .... there are enough pills to last me a month if I take one a day. I want this quit to be my last one. And I am confident Hubby and me will survive!
