There is some kind of serious 2 day bug going around now that causes the same symptoms, high fever, chills, severe body aches, and liquid coming out from both ends most times uncontrollably. but make no mistakes it is a bug and a buggar at that, should only last 2 days but it is the dehydration that comes with it that is the problem, but you can't keep anything down. This is what hit and knock down the never catches anything super man last month. The bad thing is they won't give antibiotics for a virus doesn't work, just drink as much as you can take some tylenol and get some rest, you should start to come around in a few days. anti nausea pills and some of that (i can't think of the name right now) anti diarhea medicine should help a bunch in keeping your fluids in.
