When with us for a solid week, SD was able to lose 5 pounds (with little exercise). SD went back to BM for the weekend to go to a water park and nature preserve (so lots of movement and physical activity) and managed to gain every pound back. What the hell? Her pants we just bought that were fitting are now too tight. SD said she took her medicine the whole weekend. How do you gain 5 pounds in 2 days? I didn't know that was possible!
