Keep hydrated: Your fear is expected.Yet you know you must or it is hospital time. Spend your waking hours sipping small amounts of hydration fluids continuously.Never take enough at one time to stretch the stomach and trigger emesis.If you can nibble at steamed rice or pasta without sauce you can get some energy.Your doc may be able to send out some meds.If you don't pee at least every 12 hours, get evaluated.
