Just to post a quick update on my own progress, I've lost another pound this morning. That puts me at 311, and a total loss of 47 pounds. This is the most weight I've ever lost in my life.
I lost a good 40 pounds back in high school, but I'm actually still heavier NOW, even after 47 pounds, than I was when I started back then, which was 280. That's pretty depressing.
I've just got to take it one pound at a time. I'll get there.
