That is great!!
Yeah, I'm a totally scale-aholic too, LOL. I find that it does help keep me in line though!
It's hard to see the changes in yourself, but trust me, others most likely DO see it! I have been taking weekly pictures, and can't really tell a change from week to week, but I can definitely see a difference when I compare me right now to my very fist picture taken a few weeks ago.
Keep up the good work, you're doing awesome!
