"Today is my one year anniversary of being smoke free - thank you Chantix! I took this for 3 months, and weened myself off of it the same way I began it. I also cut the dosage down to one pill a day at the 6-week mark. I checked in with my doctor after a month about depression (this and and the weening off of the medcine I believe are very important to success). I had some tough days, but really clear thinking and the ability to say no when a craving would come over me. I smoked for 35 years...If I can do it, so can you!"
