I had a pre-op diet that was full of regualar food. No liquid protein and no shakes. My NUT said that she would not deprive her patients of food prior to surgery. With that said right after I started my Liver Detoxification diet (pre-op) we had a planned Disney vacation for my childrens birthday and my anniversary. We went out to Outback Steak house and I ordered a full dinner. It was a decision I made in advance and knew what I was doing. 15 days later I had surgery and my liver was very small. So, did I cheat, I guess so, but it wasn't a sneaky I have to do this type of thing. It was a preplanned, I want to celebrate like we had planned for the past few months type of cheat. I have no regrets.
