If this has been going on for five days its past time to see a doctor and theres no "medicine" for the flu or a stomach bug, it must just run its course. It could be a number of things, stomach bug, flu, pregnancy, etc. You would need to see doctor to find out whats wrong. In the meantime sprite, 7up, or powerade to keep hydrated and try and much on some dry toast and crackers.
Well I think the flu is goin around my daughter been throwing up for 6 days now, she goes in to get rechecked today, the doc said flu last monday
You might have some kind of stomach flu. You take some good medication, or go to a doctor and he will diagnose you, and tell you what to do.
