Girls, on Saturday from 4 am till 3 pm Sunday was diarrhea and vomiting, I didn't eat much for two days. Drink water, it hurts. And now for two days I seem to be eating but still feel nauseous and my stomach hurts around the belly button like a spasm. Probably poisoned, yes. What should I do? But I took one tablet of No-Shpu today because my stomach hurts so much. Has anyone had something like this?
