I ate cereal and a banana and now i'm throwing up and have really bad stomach aches?

Stomach flu: Is an intestinal infection and symptoms are: diarrhea, abdominal cramps, nausea or vomiting, and could be fever. There's no effective treatment for this condition. The common complication is a loss of water and minerals. Good rest and drink enough water to replace fluids. Rec.: if you're not able to keep liquids down for 24 hours see a doctor.
