Today starts my 4th day on the 2 week liquid pre op diet. I cheated a little yesterday by eating 1/8 cup of plain veggies, no butter, no sauce, or anything else. I'm worried I've really messed up! But also, I am struggling! Around 6 pm, I start to feel starved. I really don't see how people manage to do this perfectly ft or the entire time frame. I need help!
