I don't have a hangover! Dunno where this has come from, Yuck! Have felt off all day but just put it down to not getting enough sleep, and just had a handful of plain crisps at lunchtme so what came up was all yellow and biley ewww! I never get ill - what is this and how can I make it go away?! We tell the kids if they've thrown up, they can't be in school for 48 hrs. If I feel okay in the morning, am I all right to go in? Is there anything grosser than vom? Yuck yuck yuck!
