I'm not sure what I have wrong exactly, but at certain times after I eat, I immediately get sick. (Stomach pain, diarrhea). Tonight I ate dinner and then within 10 minutes had stomach pain and was in the bathroom. I hate that this is a problem. I had my gallbladder removed 7 years ago, so it's not that. This sometimes lasts only a short period of time, while other times it goes on for hours.
