Be sure to supplement and follow up with with good probiotics to build the friendly reserves... acidophilus, bifidum etc... yogurt and kefir are two good sources of things like that, raw sauerkraut is very good for your stomach as well, easy to make if you can't buy it, plenty of recipes for that on the net (salt and cabbage) and should cure the heartburn too. I'd stick with the food sources for probiotics as opposed to pills or capsules.
