Almost forgot to post: down 1.6 pounds this week. Didn't get all my exercise in, but I started walking everywhere and using stairs (even carrying my backpack) at school instead of elevator, and I played some HARD racquetball, plus I bowled. Progress is slower than I would like, but it's in the right direction.
[Update] Oops, I forgot to post the total; to this point I've now lost 7.2 pounds. It doesn't look like I'll make my 15 pounds goal by my birthday, but I'll be close!
