Great posts, Audrey and JC! It's all about getting to know your body and how YOU react -- to foods, exercise, sodium, TOM etc. The scale is just a measurement tool, just like a tape measure or calipers or pants.
Believe me, I have the same hang-ups about what the scale says but I'm working on not letting it affect my mood or worse, letting it sabotage my eating.

(you know, scale down = happy, scale up = to **** with it!)
I think a lot of it is a cultural thing -- we're bombarded with all the media glitz about celebrities and models who weigh 102 pounds and we look at that number on the scale and think we're enormous. But we LWL need to remember that much of our body weight is muscle and that we can be smaller than someone who weighs much less (and has a higher BF %).
I think we all have to come to our own terms with the scale. For some people, it works best not to weigh (or only rarely) and to use something else as a guide, like pants. For others (moi

), it's every morning, first thing. Just try to keep it in perspective. Like JC said -- it's just an inanimate piece of metal and plastic.
