When I started Atkins I quit smoking at the same time and took Wellbutrin, I lost more in that first month (which is the same amount of time I took the medication) than I have in all the months combined after...I did not affect my loss at all. By the way, I think being on Atkins actually helped me quit. I know they say doing a diet and quitting is not a good idea (they are both too difficult to do at the same time) but I honestly think doing Atkins actually HELPED me get over the cravings.
