Varenicline
"I started Champix in November 2015 I have been smoking for 20 years! Stopped on day 14 and have had hardly any cravings at all. Side effects were intense to start but worth it, nauseous, tiredness and the odd crazy dream. I am now on week 6 and thinking of lowering my dose. Can't believe how easy it was to stop with this medication! Only thing I am concerned about right now is my weight loss, I have lost over 1.5 stone since starting Champix, it may or may not be connected to the Champix."
