I am starting my preop liquid diet on Wednesday Jan. 8th :0 I have been researching many different methods of Protein drinks. I came across a liquid drop which gives you 42 grams of protein in a 3.8 oz. serving. It is made by New whey Liquid Protein. I found it along with many other Protein Drinks.Needles to say, I have filled my basket! Anyone tried these? I found these on a website called Bariatric Choice.
