I've noticed that lots of people have been claiming that Champix is a miracle drug to help stopping smoking.
On the CAG threads there were loads of people who seemed to be giving up quite easily. Give up smoking - here. - The Consumer Forums

But I read that it can cause depression and maybe have other side effects. Is that true? Can the people who have actually tried it tell me a bit about what it did to them.
I get a bit worried about this kind of drug.
