Can anyone tell me more about Zyban? Like have you had side effects? Blood pressure problems? My directions say take 1 for 3 days then 2 daily after that? See what I get for ordering them online... instant, expensive gratification but too damned scared to follow through! Also, I quit yesterday, and I am hoping the Zyban will keep that panicky feeling at bay. But the directions say I was supposed to take them in advance of my quit!
