I always thought food poisoning was like a bomb going off in your body......that is until I got Noro (which is like a wmd). Luckily both of these horrific illnesses only last a day or two. My heart goes out to people who catch it on their vacation. Many people only make large trips every 10 years or so when they save money or for special occasions in life.....such a shame to build up a vacation in your mind and then be absolutely miserable.
