"I was 23 when I went on champix, I chose day 8 to stop but when day 8 rolled around I had one smoke left in the pack so I just said to myself this is the last one, from that day forward I haven&#039;t touched a cigarette and I feel great. As far as symptoms from taking champix goes I just had quite severe nausea when I went up the dosage and found that I needed to eat prior to taking and then eat a small amount straight after and usually that would keep the nausea at bay. But the nausea now was all worth the success I&#039;ve had from it. I had no other symptoms apart from the nausea and I didn&#039;t even finish the pack like your supposed too when I felt confident enough I completely stopped taking the tablets all together. I would highly recommend!!!"
