I'm only 3 weeks out, but I usually get 60 oz in. I've started using ff cottage cheese in my shakes. It makes them really creamy and they taste like cheese cake. So, I do 1/2 cup ff cottage cheese. 1/2 cup ff milk and a scoop of Protein powder. I split that into two 4 oz servings. I cover and refrigerate my leftovers. They keep and even get thicker. I've even using jay Robb shake mix. So it comes to a out 23 grams of protein for each 4 oz serving. You can also use Greek yogurts instead of the cottage cheese, but I don't like sour chocolates or vanillas. So, I save the yogurt for the fruit flavored shakes.
I also add 2 T of unflavored protein powders to anything I can hide them in.
