Long story short been ill all day today.
Just horrendous stomache ache, nausea and multiple bouts of vomiting - nothing else (no diarrhoea, sore throat, or coughing etc.). Although its only now I've been able to keep down any fluids and just about managed some toast.
I'm at uni but I don't know what/if there is an incubation period? Last bout was around 4ish. Its been years since I've been ill like this :(
Idk if I can manage any lectures or amything tomorrow though yet.
