"I've been smoking for 50 years and was up to 2.5 packs a day, it was time to try to do something about trying to stop or slow down. I looked at chantix on the internet and the side effects scared me. I talked to a few people and they said it worked to help them cut down but they didn't stay on it because they had nightmares. I decided I would give a try so called doctor and received a prescription. Followed directions and it was probably one of the best things I did in my life. After one month I stopped smoking  completely and have not had one in 6 months. I staying on chantix for 3 months never had any side effects for myself. I just want to say thank you for chantix you probably gave me a longer life and I feel so much better."
