Hi all, ive just had my second band fill today so back on liquids for three days and than puree for three days, but my question is this- can you buy such a thing as protein shakes and if so where do you get them from as i am apparently not having enough protein in my diet and even though i am losing on average 1lb per week i have lost muscle mass and as i am now on liquids i'm not quite sure what to have. I would be grateful for any advice. julie
