Surgery on April 30 :)
Yikes, three weeks of liquids! I went to MI Hospital in Tijuana with Drs. Cabrera and Valenzuela. They recommended two weeks of protein shakes for breakfast and lunch and chicken and salad for diner. Liquids only three days before surgery. I am not saying you don't have to do what your doctor told you, it is just interesting how different surgeons recommend different diets. There is definitely not a standard protocol. Best of Luck.
I had my surgery Dec. 10, 2012 in Missouri, and I was put on straight liquid protein shakes for two weeks prior to surgery, so three weeks isn't all that far-fetched. I lost fourteen pounds in those two weeks and got really crazy on the forth day. then it got easier.
Best wishes.
