yEP, I think that's what they mean by the irritable in Irritable Bowel Syndrome. Used to have this everyday; would start off C (little rabbit turds)and sometimes in the same sitting turn to very soft or runny. Things have improved some due to?? my best guess is regular exercise, high food source fiber, acidophelous(sp?), Caltrate, good luck...Urgency still when I need to go but not as loose as often.Since IBS is a motility problem, it can run the gambit quickly and unpredictably. If they could explain it they could cure it.
