I finally got a treadmill! I looked on craigslist yesterday and some guy was selling it just 4 blocks from my house!
And, despite not getting any sleep, I still did get up early this morning and walked 1/2 mile. I know that's not a lot, because I used to be able to do 3 miles, but that was about 40 lbs ago.
Also, I'm really concentrating on monitoring my calories today. I think I'll be within "budget"
