Pre-Op Liquid Diet questions

My first meeting with the doctor is a little over a week and I am researching info on the Lap Band procedure including what will need to be done pre-op. I have read on various forums here about a 2 week liquid diet or a 2 week high protein, no carb diet leading up to the lap band surgery. I think it depends upon how high your BMI is, which of the 2 options the doctor will put you on. My questions are about the 2 week liquid diet.  1. Is this only clear liquids, or does it include creamy soups, etc. 2. Are only liquids allowed for each meal? Or do you have liquids all day long with a meal a day? 3. Is there a limit on the liquids a person can intake at a time? or a limit on the total amount of liquids for the day? Thanks, ~ Tammy
