Woke up to be quite sick in the middle of the night. After a thoroughly unpleasant experience I've been ok since (not feeling awesome but not being sick/dieing). Does that sound right for the winter vomiting bug? I was under the impression that once you started you didn't stop for a couple of days, and was suspecting a bit of food poisoning instead?
Of course, working out what's going on could have a serious effect on Christmas dinner!
