Yesterday, I had the onset of sudden rather violent diarhoea (sp?) - sorry if TMI. Feel really knackered and headachy like I've got a hangover, but apart from that and still having the squits, I feel OK. No sickness and am still hungry. Oh, also have had the strange experience of cereals and bread tasting very salty. Anyone else had this? Is it the norovirus, but without the sickness? Can you get norovirus without sickness. It's really weird - like I'm ill, but I'm not!
