I do not have my DOS yet, but was wondering....how much skin does everyone have "flapping" around? I am as active as a fat person could be now and plan to be even more active after....will i need to wear Spanx?

Fortunately, I do not flap, although I have "granny arms." Most of my skin looks loose although it seems to be tightening up a little in the stomach. My butt, however, has deflated and is sliding down the back of my thighs. I lost 94 lbs, but I'm 57 and gravity has helped things along for a while now.
