"My 11 y/o son requested me to stop smoking.  Cold turkey and other alternatives is so hard to do it until I asked my PCP for some help.  She prescribed me Chantix since my husband's insurance covers is 100%.  Took it for a month and finally was able to stop coz cravings/urge are gone.  Only side effect I've experienced is severe headache so my PCP advised me to talk 1/2 dosage since I am small and petite and it works.  Smoke free for 10 mos already.  Thanks Chantix!"
