i have the Rx also..havent taken it yet because i dont have it in my mind that i want to actually quit just yet..however, it does say for the first 2 weeks you can smoke while taking the med..i think it is to set a "quit day" and to have that as a goal..i have 3 friends that took the med and 2 have still not smoked and it has been almost a year..the other one the med made him sick and he started back smoking after 3 months of being smoke free..best of luck to you on your goal to quit
