Dear Marilyn: Don't know if you're referring to me, Karenj, (just added the "j"), or ???? But I'm responding anyway. I have taken wellbutrin now for two attempts. It always helped the quit smoking attempts, but this time around I'm actually taking it full on to help make this a permanent quit. I, too, wound up with gas and farting, but felt it was more due to my body expelling excess carbon. The heartburn left me as well after a few weeks. I believed that both were primarily due to the smoking, not the wellbutrin, but it's different for everyone. Last time, I only quit for two months, but realized at some point that I was no longer gassy, farty or using my inhalers at all. What got me back on the drag was stress.
Also, as a smoker, I was more prone to eat junk food (salt, sugar and fat)--anything I could taste. This time, I'm eating heathier--fruits, nuts, raw veggies, fish, less fat content beef, less coffee and more CHOCOLATE! And, yes, the chocolate can be a boon or a bane. Good luck. Karenj
