"Smoked 20 a day for 30 years now onto week 7 of the program and still off the cigarettes. A few cravings but do not last long. Problem is possible side effects, get nausea which I can live with, feel as if I have a constant cold but worst are the aches in the joints anyone getting these? On the upside I am sleeping better than ever. Am cutting down the dose to see if this helps."
