Thanks for that, is what I was thinking. However I think it is actually a mild gastro sort of bug. I was kept awake all night last night with my stomach making constant really loud gurgling noises and kept getting up thinking i was going to have an accident but just ended up passing really foul wind - and every time I rolled over it was like my stomach was full of gas and the pressure of rolling over would let out this foul eggy burp. Was really gross - have only managed to eat a piece of toast today because I just feel so wrank!
