Oh, you lovely people are kind. Yes, I've had it twice, anno and have been so careful about hand washing and taking precautions! but it got me again. I keep hydration sachets in, fortunately, so started on those even when they weren't staying down.
I was shocked to hear an acquaintance who has had norovirus at the same time as me commenting that she was going in work today, as they are short of staff - a school dinner lady! 'It's only a couple of hours' she said. As soon as she walks in the place she will be sent home (the manager has been tipped off). No wonder it spreads when people behave like that.
