I think I have a virus. I had the worst indigestion all day yesterday, and I thought it was just something that would pass. I woke up at 1 this morning throwing up and have been throwing up since here and there, diarrhea... trying to keep down liquids, but don't know if I'm getting enough. I don't really know at which point I should call the doctor.
