hi char. i did the same thing with chantix. i took it as prescribed (twice a day) for a month and a half or so then i thought i was strong enough to only take one a day... well here i am again. i too slipped. i didnt go into a full blown relapse. i think i smoked two or three for four days or something like that. anyhow im back to taking it twice a day, and by the thrid day, may cravings have improved. so yea i personally did notice a difference, but i also noticed a difference in my mood too. im not to sure what to blame it on. probly a little bit of everything. anyways. good luck! your not alone.
