I had it once. I realised it was coming on at my sons 3 hours drive from my own own home. Grabbed all my gear said my good byes thought I was going to make it all the way home. Sadly 15 miles to go and it was long stop in a layby followed by another at 8 miles away.
Warning it is very infectious. Brother and S.I.L stayed one night, I kept well away from the them separate toilets etc but they still got it.
Norovirus was the sickest I ever felt - by a long way. Caught it over one Christmas - was so ill on my 40th birthday (29th December). We had a trip to London planned with theatre tickets and swish hotel etc and instead my head was in a bucket over and over and over again.
