I am in the process of reducing the amount of nicotine I take into my body but soon I will get to the zero nicotine and plan to use chantix to nhelp when I get to the zero nicotine part of quitting. Those of you who have taken chantix, can you give me any suggestions. Do you have any concerns? What was your use of chantix like? I know everyone reacts diffrerently to the drug. But still would like to hear about your chantix experience.
