Immediately after work yesterday, I came down with something that's gotta be exactly like norovirus. Firehose diarrhea. Pounding headache. Fever. Chills. And then, around 7 pm, dry heaving. Light-sensitivity. Even the light from a television screen or my laptop monitor makes my head and eye sockets ache. It's a beautiful day outside and I can't even make it to the car without having to turn around and run back inside. All I can hold down is water and I can only have a few sips at a time. Can't even go to the pharmacy to get something, anything to abate these symptoms. Anyone else have this? How long does it last?
