Even if you don't like oatmeal. Try some with bananas. Drink lots of water, you don't want to become dehydrated or you could wind up in the hospital. Have you called your doctor's office, or call your pharmacist, they could recommend some over the counter.
Did you eat chicken within the last 36 hours before coming down with it. If so, that is the culprit.(this info came from a physician)It is normally food born. If it is a virus, it should be gone in a few days.If it is a bacteria from food or food handling, you need to be taking perscription medication.
