So, not my best effort ... but if you will indulge me, I did have two unexpected events this weekend, and I did choose poorly at times when I was there.
On the other hand, I was "too tired" to work out Monday night. (I did nap for about 90 minutes, but it wasn't like I couldn't have pulled out Wii Fit afterward.)
Besides, I know that I'm making progress. One of the things about weighing myself in the afternoon (we have morning and afternoon weigh-ins to catch people on either side of the workday; I pick afternoon because getting here early is not my idea of fun) is that I know it'll be more variable: what I had for lunch, how I've been drinking water, etc. But when I weigh myself at home, it's in the morning, and I do use Wii Fit often enough that it gives me a decent picture.
Still, it would have been nice to hold steady last week ... then again, I weighed myself here at work this morning, and I was 3.5 pounds under what I weighed yesterday. :)
