I had not had D for like a month until last night, had been taking Medimucil and that seems to keep me regular, 3 times a day of normal stools. And then last night out of no where I ate a Subway and like 2 hours afterwards I had D all night and Nausea as well. I managed to fall asleep around 1am and when I woke up I had D again, which isnt usually how it goes if I have a flare up, the next morning its usually fine. its almost noon and I still don't feel all that well. Any ideas?
