My surgeon requires 3 weeks of protein shakes and crystal light. Supposed to get 80-120 grams of protein per day. They say no to everything else. Just left the office from my first weigh in pre surgery. Finished my first week of no food, two more to go... this is tough! I definitely agree, more stressed about the pre surgery diet than the surgery its self. After surgery our stomachs will be smaller and we will not be so HUNGRY.
