I Had Either Food Poisoning Or A Stomach Virus Two

I had either food poisoning or a stomach virus two weeks ago. I ate pizza with black olives and pineapple on it (olives tasted metallic). Within three hours, I was doubled over in pain, vomiting and diarrhea. Lasted about two days. Since then, my stool has been very light mustard colored with a whipped appearance. I have no gall bladder.
