Southern Belle is probably right, you have things stirred up in your body. However, burping is definately a symptom of gall stones as can be found in any medical information. Now that you loosened up your stones they are probably fallen over the ducts (not allowing bile to flow as well)and will cause burping and some indigestion for quite a while until you get rid of them all. But I can certainly understand your irritation of it. I've had this problem since April. I've made progress by doing Liver Cleanses
but it is very slow. Hang in there.
