I am on Day 2 of my Pre-Op diet and I am STRUGGLING. I feel like I am starving. I am so hungry. The shakes are doing nothing for me. I hate drinking them. I am drinking my water, but the hunger pangs and headaches seem never ending and it is only DAY TWO. My surgery is on June 9th. I hope I can make it the whole two weeks. Did anyone else struggle with the Pre-Op diet? Did you cheat?
