In all that huge pile of permissions/acknowledgments/etc. that we sign before surgery, there should be one form, typed in huge block letters, that says "please sign below to indicate that you have been told that your scale is a b***h!" Then that page should be framed and hung above the scale.
You are losing fat. You have to be. You're not eating enough to keep a good-sized gerbil happy. However, on the grand platform of hormones, swelling, fluid retention, and just plain contrariness, the scale isn't showing it right now. If you haven't already, please take your measurements! There is hardly ever a time where you don't lose either pounds or inches! Having a second source of confirmation helps to keep you from getting discouraged. ((hugs))
