Thanks for your response - it was really appreciated. I'm feeling a bit 'off' this evening. It didn't help that the woman I sit next to at work went home ill but everyone said it was a cold (she did sound pretty bunged up and she'd had a bad nights sleep!)

The girl who has been off for definite with v* didn't show symptoms at work and is still off (it's been three days) so starting to think it could be something other than noro..? I don't want to think too positively though and then it'll turn round and bite me in the bum!
