I've been put on a two week pre-op liquid diet. I haven't been able to tolerate the Protein shakes. I've bought and tried them all. Makes me very ill. I want to be healthy and I worry about my nutrition. In fact, that is my number one concern is my nutrition. I am nauseous, not hungry and don’t even want clear broth. However, I am getting in my Water. This is going on day 7. I’m very worried that I won’t be able to get in all my protein after the surgery. Has anyone else experienced this?
