Despite another rubbish night of sleep I'm feeling a lot better today as am fully in control of my bowels. Sorry for my whinge yesterday and thanks for the comments. Sleep deprivation does funny things to the mind. I can see why they use it as a torture method! Turns out it was some tiger prawns that caused the stomach upset so think I'll be avoiding shellfish for a while.
However despite the terrible weather I've managed to get out exercising every day. Im booked on a mountain bike course all day tomorrow and the forecast shows sunshine. Fingers crossed!!
