Yes . . . it happened to me, too. Even two years later, I am generally about ten pounds lighter than before my donation. At 5'9" and 124 lbs, I'm actually considered "underweight" by some standards, but I feel healthy at this weight. I think I am eating better, exercising more, and generally taking better care of myself since the surgery - maybe you are, too? Good luck with that last 10 pounds!
