I will eat the BRAT diet after diarrhea for about 2 days, but the result is still the same. Tremendous amounts of gas, nothing being digested. I take Immodium and Gas-X, but the same symptoms persist. It's hard to get back on any kind of regular diet, and 6 or 7 days go by without another bowel movement. I've tried skipping Immodium, but the same scenario persists. What else might I do?
