My Surgery is Friday March 20, 2009. I am on the pre-op diet for my second week now. They have me on meal replacement drinks for breakfast and lunch then a small high protein, veg. dinner. I have tried my best to stay on track but have broken the rules some. I had some peanuts as snacks on few days and 1 scrambled egg with little cheese one morning. Three of the days I had a small lunch instead of my normal slim fast bar. I find myself worried about swaying from the diet. I am hoping others also have done that. Any input would help.
