I hate that. It can be SO discouraging. Just keep thinking what you've already said, weight fluctuates. It's hard when you feel like you had a great work out the night before and you're feeling great, and then you weigh yourself the next morning and the scale goes up. But what always ends up happening is you go on in a few days (or in my case the very next day lol), and the scale jumps down a pound or two.

You know, one thing that occurred to me about your scale (for anyone that's reading this, we're real life buds, lol) is the fact that you have it on carpet. Have you tried it on the plain floor in your kitchen?? They often say that you shouldn't have your scales on any kinds of carpet, because it'll change the number, even if it is a very thin carpet like yours....
