"Day 28 of taking Champix and day 14 of quitting smoking! I don't have any major side effects, other than nausea After first taking the pill,I find eating a few soda crackers and drinking lots of water when taking it helps a lot! Thank you Champix! I was a pack a day smoker for 30 years... I am 45 years old now and feel like I may have a healthier future a head for me thanks to taking Champix!"
