About 30 hours later and 3 kilos lighter, I can walk across the room without stopping for a rest. Acute gastro-enteritis sure beat the snot -and more objectionable stuff- out of me but I should be fine by tomorrow. (Spellcheck tells me 'gastro' is not a word but it looks right to me).
The Big Hominid described a stomach flu going on in Britain and when I commented that I might have it as well...nothing. Thanks for the sympathy, jerk! Oh, and it you're visiting, I can't find online the name of the crowd control gas from Blish's Cities in Flight (its effect was similar to the flu I have now).
