Well, This is it. I have documented the various measurements and my wife has made me my first breakfast of portabello mushroom, spinach and chick peas with a cup of white sugar free tea. Then packed me off to work with bottled water and 100g of cherries until lunchtime where she has prepared my meal. Wish me strength and fortitude!! Oh and a special thank you with all my love to my very special supportive wife with this adventure.
