I haven't had a "whoosh" on the scale...but obviously have in "inches".
I put on a pair of jeans this morning that were pretty tight a month ago and now they are about 3-4 inches to big in the waist, they are baggy on my butt, and loose in the thighs!!!
My DH thinks it is hilarious to see me put both of my arms in my pants to show him how big they are getting!
