Wow, congratulations on your great loss!

This topic comes up a lot, actually, so you might want to do a search on the forum on "loose skin" or something like that to see what's been posted. Often when we lose a lot of weight quickly, the skin doesn't snap back into place right away, but weight lifting seems to help some people ... for others, time (maybe a year or so) will help, and still others consider surgery as a last resort. There was a thread about this on this support forum not too long ago ... one of the posters was Mrs. Jim, you might find it that way.
Good luck, it'll work out in time. You've done a great job with the weight loss.!
