Sorry so late chiming in, just joined the forum. I've been on pre-op since Sept. 15, 2009. I have found the Lean Body ready to go shakes very tasty and protein drinks go and very satisfying. They come in Chocolate, Vanilla, Strawberry, and Banana. They provide 40g protein, 0 sugar and loads of vitamins. They are a little more expensive than others but I think they are worth it. I obtain my supply from GNC. Good luck on your pre-opp and banding. I scheduled for surgery tomorrow 10/1/2009.
