Mmmm.....animal style fries... sooooo yummy.
It's fries, a slice of cheese, with thousand island sauce on top and grilled onions.
Anyway, best thing to do is keep drinking fluids, water is good cause it instantly gets absorbed and the vomitting is just going to keep dehydrating you. What I would try to do is drink a glass of water, then a glass of soda or gatorade, then more water.. and so on. Liquids hurt the least to vomit but you will primarily be vomiting up the soda/gatorade. And anything you do process will at least have some calories/carbs so yeah... I'ld do that till you vomit less, then try crackers/bread, then non acidic fruits like apples or bananas then peanut butter (seriously, the protien is good for ya). Then hopefully you will start feeling better.
