How do people manage with doing CD at work. I do an admin role so i sit at a desk 8hrs a day. I was thinking of having a shake for breakfast and soup/shake for lunch at work. Are they much of an issue to 'make up' and do you advise i get something to 'make them up' in? I did just buy a thermos flask for soup so it doesn't go to cold if i didn't eat it all at once.
