I had upset stomach (vomited off & on for nearly 8 hours) this past Sat & had severe diarrhea - so much that only thing left was mucus coming out - ended with nearly dry heaves. Took some Pepto Bismal. Yesterday morning a little diarrhea & another Tbs of Pepto. Did the BRAT diet. This morning (Mon), real weak, feeling nauseous & one more Tbs of Pepto. BRAT diet again today, except had steel cut oats for breakfast & added spinach with lunch. Stomach feels like it s about to explode & still feel nauseous. No fever, I think, but was very cold on Sat. Figure food poisoning or stomach virus, but never had it last this long before.
