Hi, im having diarrhea for 16 hours now and it will not stop. Yesterday I had headaches, and high temperature. My diarrhea has green color and black spots in it. I took activated charcoal (125 mg) 6 times now and probiotics. I have a water clear pee. I consumed a toast at morning 6: 00 for lunch I had chowder or fish soup and for dinner I had some mashed potatoes and oranges and 1100 mg of vitamin c.
