That probably explains why my wife had what she insisted was just food poisoning last week, after she puked about 5 times in a row one morning, and refused to let me take her to the clinic.
That's true, but don't let yourself become extremely dehydrated. My sister-in-law got norovirus last year. She was delirious, confused, and exhausted from lack of sleep and water since she couldn't keep anything down. She had to be dragged to the hospital by my mother-in-law. She was admitted, given lots of fluids, and stayed a day or two until she stabilized.
