"Smoked for 30 yrs at 30  a day plus cigars and Champix is a God send. Make sure you want to quit and stick to the program and don't buy smokes anymore. Oh and think of all the extra spending money you will have, from straight away, I have saved heaps since I stopped 1.5 yrs ago and am able to buy things small and large with so much more ease and I feel better and stronger."
