Chantix
"First of all, all of those people who quit, will be back to smoking really soon. And if it says they are smoke free for years, it is probably a bought comment by Pfizer. Trust me. I did quit as well 3 times, but it is not permanent. The side effects last even months after you take the pill. the last time I quit with it, I had a neurological breakdown, I could not control my body, I was having a non fatal stroke and even heart attack. I could not talk, had to be taken to the emergency. My eyes were rolling up, I could not control my limbs, could not talk, my mouth would not move to talk. It was horrible. Months later I am back to smoking and now I am scared to take the pill. The depression was horrific and same with  the dreams. I do not recommend"
