Holly - don't be bummed. You know how sometimes you lose 3 lbs when your don't think you did THAT good. Well, sometimes you don't lose a thing when you are perfect. We want our actions to produce resuts immediately. Dosn't work that way. I bet next week or the week after it'll show up.
I am dying to weigh in, but I won't. Not until Monday. I have been doing great. But if I weigh in mid-week and i don't see results, then it's almost reason to binge (it's not working anyway!). If I am losing then it really motivates me, but if I am not - it sends me.
Anyway - you are doing awesome! Just remember, it's a scale. It's only one way to measure. How are feeling? How do your cloths fit. Give it time!!
