Body Wraps

Since I've been losing weight recently (without cissus quadrangularis!), I've been thinking about trying a body wrap to help firm up some sagging skin. Has anyone ever tried one? I won't expect any sort of miraculous cure but it would be nice to lose a few inches from my hips. Maybe I could fit into my pants better. I have a smallish waist with a large belly (thanks pregnancy!). If I could get rid of the sag, I would be a lot happier with my body. So, anyone have opinions on body wraps?
