My five year old has had this bug since 17th dec - started with ear ache so had a course of antibiotics, started vomiting two days before xmas, stopped -, ear ache again and still today is very poorly - temp goes from boiling to freezing - she has barely eaten a thing now all that time - as soon as she starts to get better and we have a day out visiting family she goes backwards. I think the best thing is plenty of fluids and lots of sleep. With regular does of drugs. Keep resting and stay warm. You will be right as rain by the weekend hopefully - Good luck!
