I've been on Bariatric Advantage shakes for 9 days. 4 days to go, then 1 day clear liquids, then surgery on Sept. 21st. I've been doing 3 - 160 calorie shakes a day, and supplementing with low calorie organic tomato and cream of broccoli soups (70 calories a cup) which helps when you get sooooo sick of sweet stuff. Stock up on sugar-free: popsicles, gum, mints and Jello, it helps break things up a bit. Good luck!
