Day 10 - to weigh or measure?

Both me and the boy now feel ill but I refuse to stop being a better eater. Today I had a square bar, a gingerbread man as felt sick, crackers and innocent Mexican chipotle chilli. Had some nuts and seeds, stirfry from last night with tofu, cherry tomatoes and some houmous. I feel sick now though. I also weighed myself today , scales said I was 12 st 11 3/4 which was exceedingly depressing. Thought I was doing well :( bad times
