I had the colonoscopy, stool specimen test twice.  However I have had heavy diarrhea three or 4x a day. It often looks like a black mud slide. I need stronger anti diarrhea meds as I now take 6 to 8 a day now.  It is the only way I can control it. I am planning a trip. I want some really strong meds to keep this in control for my trip.  Thank you
