Something like that knocked a few people out from work a few weeks back, nasty bug as they said you spent a lot of time with a bucket in front of the toilet or in the shower. Good times. Drink pedialyte.
I had that stuff a while back coming out both ends with no stop in sight went to doc and he gave me some pills that after one I was so plugged up that I didn't go to the bathroom for 3 1/2 days... so I guess its pick your poison
