dlucia 2 Posted May 26, 2011 I was not on any pre-op diet either before surgery. I ate regular all the way till the day of my surgery (I had a l ot of last meals the couple weeks before my surgery). My doctor did say that the day before surgery I could eat a big lunch but to keep dinner light and nothing to eat or drink after 10:00 pm But if your doctor has you on a pre-op diet. I would say you really should stick to your diet. Each doctor is different and your doctor is only thinking what is best for you. Good luck Share this post Link to post Share on other sites
