My doctor put me (and all of his patients) on a 14 day diet. We can only have 5 high protien slim fast shakes a day, all the 0 cal beverages we want, clear broth, clear juice, SF Jello and SF popsicles. I am having surgery on the 16th. I dont know if it shrinks that fast. But I do know I miss being able to chew my food and really hate slim fast!!
Good luck though, I am sure you will be fine!!!
