I was awfully mad at my medical insurance (drug provider) due to them not filling my prescription out for chantix. Now I am glad that I never got my prescription filled out. I thought I would need Chantix because I thought I would not be able to quit cold turkey,but I have been successful so far. I quit April 16, 2008 and I experienced a couple of weeks of sleepless nights and bad dreams anyway. It must be because your body/brain wants the nicotin...
