That's has happened to me too, Rosie. I figured my computer gets skittish sometimes.
I think I will refrain from getting on the scale b/c my weight fluctuates 2.5 pounds and it starts to distract me. I know I am eating balanced. I know I need to consume enough calories to keep me vigorous. I don't know why my body fluctuates so much but I can not measure myself worth by a freaking number on a man made device.
Gearing up for a week-end filled with family, food and fun. I will not slip up and eat foods that side track me.
Wishing the same to all of my healthy eating buddies here.
