It sounds like you are doing a great job with your weight and health! I'm also impressed that you were able to do what you promised yourself after you graduated!
I have been following the South Beach diet and have lost 25 pounds. I have lost and gained weight all of my life, but things had gotten out of control, lol! Anyway, I am eating much healthier all the way around and trying to get more exercise. I live across the street from my brother and sil, so we ride bicycles and go swimming. I actually got an adult tricycle, and it is SO much fun
