"I started taking this medicine to quit smoking and I haven't had a cigarette in over 6 month's the best thing I could have ever done. I thank God every day for giving me the will power. Yes I was moody AND all the side effects that are listed but I really wanted to quit smoking. I smoked Newport 100s and a pack a day. I feel great and I really didn't gain any weight maybe a few pounds but I made sure I kept busy. Thankyou sincerely I'm so grateful."
