I had my lap band in may 2004 had my tummy tuck 15 months later I went from 270 to 165 in a little over a year!! My weight loss was very rapid and noticed a little thinning in my hair,,,,,I took 2 chewable flinstone vitamins and drank a protein shake a day to stop it!! Saggy skin yes it happens lol, I tucked it in my jeans until I saved enough for my tummy tuck and I love it I feel soooo great with no sag haha
