Hello, just had the Sleeve 19th Feb. I started working with my insurance company in March of 2012. I had to lose 10% of my body weight, and also I had to see 3 or 4 doctors for EKG, Stress Test, Diet Doctor, Stomach Scope, and a few other test.They approved me Dec 2012. I planned the date for Feb myself. Needed extra time to get personal things in order. Here is a tip, after you get approved and make you date, enjoy all your favorite foods a week before you start the liquid diet, that way its all out of your system.
