I concur, the timelines don’t seem to match noro or any other sudden onset gastroenteritis I have ever heard of. Could be salmonella or E. coli, those have longer incubation periods but symptoms usually last longer than that. 3-7 days for most cases of salmonella, 1 week to 10 days for E. coli. They are fairly rare but you could have had one of those, or a respiratory bug. High fever along with post nasal drip and coughing hard could induce a round or two of v*.
