I'm on day 3 of my pre-op diet. It is definitely not easy to stick to but I've been good so far. My surgery date is March 1st and I'm going to stick to this diet. I've been fine on this diet during the day time, while I'm at work. When I get home it's a different story, then I have to prepare and smell food which makes it hard. We can do it though, we just have to be strong. Good luck
