I started Champix 8 days ago, on the first day i took the 0.5mg tablet and was surprised that the taste of cigarettes was awful an hour later, i thought this is how it would remain.. however, day 2 the taste was normal and since then i have not really felt the positive effects... i have felt many of the negatives ones, terrible dreams and i wake up still thinking i have actually lived everything i just had the dream about. The anxiety is terrible, however, i take a 1/4 of a tab of Xanax to overcome that problem... i also had a few hours of rather manic behavior which is just not me... i gave myself the stop date of day 8 which was today, however, i felt the need to change that as i really don't feel that the tablets are having any positive effect. Has anyone else had this issue?? Will they kick in soon?
