i had this the other week. is horrible. i sipped small amounts of ice water and had a few lucozade sport drinks to rehydrate. and just stay in bed and rest.if you have diarrhea try dyoralite(sashets you mix with water)
Eat healthy... If infection is serious such as severe diarrheo, vomiting and severe pain in stomach... Also if u feel ligh headed, blurry vision, spit blood or have blood in ur motions... U ll need antibiotics.... Other than that drink plenty of fluid coz small amount of bugs can cause dehydration... Of u cant keep anything down try eating something more fluid such as soups etc... If it remains more than three days and no changes appear seriously make an appointment...
It just has to run its course. Usually it shouldn't last longer than a day or so. If you're unable to keep clear fluids down and are vomiting or have severe diarrhea you need seen to make sure you're not dehydrated.
