I had food poisoning twice ,one time worse than the other. The second time i had it, i had symptoms much like what you describe. My doctor told me to try to eat yogurt. He said the good bacteria would actually help my stomach to feel better. I did try that and it did help. Maybe you might want try that and see if it works for you. Fluids are definitely the most important thing you need right now or like you said, it will be back to the hospital. I hope you feel better soon <img src="i/expressions/face-icon-small-smile.gif" border="0">
