I have no interest in reading the article you posted. But since you did ask for an explanation for my “Other” vote, I’ll explain: I have IBS both C+D. So it’s rather unpredictable. Sometimes I will have diarrhea every day for months. Sometimes I’ll be constipated for months. Every few months or so, I do have diarrhea where my stomach hurts to the point where I sometimes nearly pass out.
