I'm on day 1 of my pre-of diet today -- full liquid for 10 days. Protein shakes, sugar free jello, broth soups (no cream soups), crystal lite, skim milk, apple/orange/grapefruit juice (up to 2 cups a day combined juices and milk + shake amounts of milk). Could be a long 10 days. My surgeon says it is especially to shrink the liver to make the surgery easier and give a boost for those first few days.
I had a similar experience with the dietician -- absolutely the ONLY one of the "team" to make me feel like that. I only see her twice -- that first time and then once after to get the long-term diet plan. Just trying to convince myself I can do anything just one more time!
