When I was on the clear and full liquid phase, it was a life saver (I'm referring to the Isopure clear beverages). It's not the greatest tasting stuff ever, but better than some other choices. I also found that it was better very cold or over ice. Some people have problems with cold liquids after surgery, so be careful with that. I drank at least one everyday while on the liquid phase. It helped to get in protein requirements and curb hunger pangs. I have only tried the Fruit Punch and Grape Frost. Personally, I liked the grape the best, but that's a matter of personal taste. You can order other flavors from GNC and other places online, but I think you have to buy in bulk. I don't use them now that I am on regular food, though. They are expensive and feel fuller longer with food-which is how the band is supposed to work. Hope this helps.
