What can i do to get rid of stomach flu?

Nothing: It is a viral infection and must run its course. Can treat symptoms (nausea / diarrhea / muscle aches / fever) to be less miserable. Try to remain hydrated to keep up with fluid losses. Can use chewable anti-nausea medicine for help (like dramamine (dimenhydrinate) / bonine / etc.). See dr if vomiting to point cannot keep liquids down, lightheaded, or bad abdominal pains.
