Oh it's gonna happen...and when it does you'll probably see the scale doesn't move but you go down pant sizes like crazy. That's the way it has worked for me.
I find I've gone back and forth (I'm just over 3 months post-op). I'll have a few weeks where I lose pounds and some inches, then I switch and don't really lose pounds but I shrink.
Odd phenomenon, but I'll take whatever I can get (rid of).
I've noticed the same thing. I'm still wearing the same clothes as before, and the only place that's gotten smaller is my waist by a little bit. It's definitely disappointing, but I know that if I keep on track, my body will catch up with the scale!
