"70 days smoke free so far, started taking Champix on 1st of Jan, 2015 - best decision of my life. I've tried other quit-smoking aids (gums, patches, e-cig's) and nothing worked. With Champix it wasn't even an effort to quit - seriously, after about 11 days into treatment it was becoming a drag to even go buy cigarettes let alone smoke them. Regarding adverse effects, in my last 3 weeks of treatment (took Champix for total of 6 weeks) I began experiencing nausea when taking the pills without food - the nausea was rectified when taking the drug with an adequate amount of food though and I experienced no other adverse effects. I smoked for 4 years, up to 2 packs per day. 10/10, Champix saved my lungs and I couldn't be happier!"
