TMI alert! Have had a very bad tummy bug and am left in a position where venturing more that 30 seconds from the loo would be a foolish risk. I've decided that the water I'm drinking is passing through my body at great speed so in a rash moment I've swallowed a round piece of floaty plastic to time how long it takes to come out. I'm mad aren't I, too long on the sofa with only flat lemonade and salty crisps for company I think.
