Could my sons' vomiting and other symptoms be more than the flu? My three boys are taking turns keeping me up nights vomiting and some diarrhea. They will sleep for a few hours and wake up with a gurgling stomach, and then have uncontrollable bouts of vomitting. I have changed the pillows in the house, cleaned all the sheets, disinfected the entire house.  My husband has had a few of these symptoms as well.  I have remained immune.  The doctor calls this a virus, and I tend to believe him.  However, this has been going on for weeks, and I am exhausted by doing laundry in the middle of the night, every night.  It changes which boy every second or third night, and then maybe a night off, and then another.  Any clues?
