"I was prescribed Champix by my doctor and started on the them on the 12th January. I had to pick a date as a quit date, I chose the 25th Jan. I was a heavy smoker for over 20 years and on 2 packs of 20 a day (awful) I am proud to say I am a non smoker after taking Champix for just 12 days. To me this medicine is a pure miracle, I have to finish my tablets which were to last for 14 days. I have had headaches and really bad dreams that have woken me but I can live with that, I have no cravings at all to smoke and the thought of it does make me feel a bit of nausea. I just pray this last's as it truly is a miracle medicine."
