I quit using champix just before New Year's Eve. Had a sneaky puff a couple of days after, but nothing more since then. I was a vv heavy smoker, 30, 40 rollups a day. Who knows, maybe more sometimes? I used to wake up in the night to continue my smoking habit. 
I still have terrible cravings. They have been worse over the last few days. I feel really angry and upset. I also feel quite fat. I have not weighed myself because i'm too scared. Suffice to say there's Crimbo and Quitting smoking poundage, so probably 8 to 10 lb. To be frank, the fact that none of my niec clothes fit me properly also makes me very angry.
However, generally I feel upset and angry and miserable and would love a fag. I also have spots and I keep getting a horrid taste of stale tobacco in my throat even though I haven't smoked. I have a sore throat, cough, feel miserable and fat and I have spots. I wish I had never stopped. I took Champix and that made me feel awful.
I'm seriously considering going to get some baccy, because I was happier and a nicer person as a smoker! Where is all this renewed energy and vitality they go on about? Aren't you supposed to turn into Supeerwoman? I feel like fuckin chuff!
IABU to exected to be feeling better and healthier after 6 weeks without smoking?
