My surgery is scheduled for May 15, and i am suppose to be on my pre-op diet. I'm having a heck of a time with this!! I'm suppose to loose 13 lbs. post surgery and i have lost 10, however I'm still not following the diet that the OCC gave me. Does anyone know if its okay if you don't just have liquids only before surgery as long as I'm losing what I'm suppose to before the surgery?
