My Christmas miracle turned out to be a fraud. The floor in our house is very uneven (classic student ghetto housing issue), and I've noticed that if I put the scale down in the wrong place I can get a crazy reading. So I've decided to move all future weigh-ins to the bathroom, which has a hard-tile floor and thus is a bit less prone to wackiness than the hardwood. I think last week's reading is the bad one and that this week actually went fine. Still, grrrr.
