"I was only 2 weeks on Champix, I was planning to go on more than a month but that all changed after day 9 when I exercised will power and quit smoking any small amount of cigs I still smoked. The first 3 days were the worst when it came to cravings but they were bearable compared to the cravings I had when I was trying to quit without Champix. Honestly, one of the best things I have came across. I only had minimal side effects such as nausea and headache and I felt extra tired so usually went to bed earlier but I did not mind any of those! I am so happy that I am now 9 days smoke free and barely get any cravings and even if I do they go away fairly quickly! I can finally say I am smoke free after 8 years of 20/30 cigarettes a day!"
