Hi! I've been on a liquid diet for 2 weeks prior to surgery *Aug 19* and I was allowed to have certain protein shakes, broth, sugar free jello and sugar free Popsicles. It was great! I really didn't have any problem at all. I think I dreaded it more than anything. I feel so lucky to realize I can be starving & a little 11oz shake can satisfy me. I lost a little over 20 pounds but still have a couple days to go before surgery. I stuck to it 100%
