Guinea-pig Week 1, Day 1

Presenting myself at the hospital at 09.30 this morning I lasted a pathetic 15 minutes on a exercise bike wearing an oxygen monitor and having my heart-rate noted at 30 second intervals. 

I have been provided with the necessary kit to take and store poo and urine samples, and given a food diary in which I must note everything I consume during the next 7 days. I am embarrassed to write in it tonight that I have had five Lindor Chocolates (Extra Dark of course!) 

Tomorrow I will do better - especially as there are no Lindors left!
