Felt perfectly fine yesterday, then all of a sudden in the evening I felt really nauseous and was very sick a few minutes later. Was then sick at half hourly intervals for much of the night (heaven knows where it all came from). Not projectile vomiting though. Also diarrhoea started a few hours after that.
Felt (and still feel) 'fluey though - shivering and fever, aching limbs, etc.
And if it is norovirus is there anything I can do to reduce the chances of the dcs getting it?
