I guess I'll be the exception
I had two packets of instant oatmeal last month and I felt incredibly sick for the next two days. I'm not sure if it was all the fiber, or something else entirely, but I know the oatmeal didn't agree with me. I've got quite a few serious strictures in my small intestine, so the oatmeal might have contributed to a partial obstruction of sorts. If you're doing well with the oatmeal though, keep it up! Peaches and Cream was always my favorite flavor!
Good Luck!
