(Reason: sleep often empties the stomach and relieves the need to vomit.) When you awaken, resume drinking liquids. Water works best initially. Clear Liquids: Try to sip small amounts (1 tablespoon) of liquid frequently (every 5 minutes) for 8 hours, rather than trying to drink a lot of liquid all at one time. Sip water or a rehydration drink (e.g. Gatorade or Powerade) Other options: 1/2 strength flat lemon-lime soda or ginger ale After 4 hours without vomiting, increase the amount. Solid Food: You may begin eating bland foods after 8 hours without vomiting. Start with saltine crackers, white bread, rice, mashed potatoes, cereal, applesauce etc. After 48 hours on a bland diet, you may resume a normal diet. Avoid Medicines: Discontinue all non-prescription medicines for 24 hours. (Reason: they may make vomiting worse.) Call if vomiting a prescription medicine. Contagiousness: You can return to work or school after vomiting and fever are gone. Expected Course: Vomiting from viral gastritis usually stops in 12 to 48 hours. If diarrhea is present, it usually continues for several days. Call Your Doctor If: Vomiting persists for 48 hours Signs of dehydration occur You become worse or develop any of the "Call Your Doctor" symptoms.
