I've just had it, or something very like. Acidy tum and nausea, then temp started, then violent (and I mean violent) vomiting, then high temp for a day, bad headache, horrid body aches etc.
I seem to have escaped the diarrhoea part, at least. Still feel sore inside (food hurts going down, and am very windy!) but starting to feel less wiped out, three days later.
dh on the other hand has had sore stomach, nausea, no diarrhoea, no vomiting, temperature for 24 hours and backache.
dds have had nothing at all (touch wood).
It can and does vary from person to person depending on viral load, and strain.
So yes, you poor love, you might well do. Get well soon.
