I've been getting in more than the 80 oz. Fluid since post op day 3 and I've been getting 75g protein too, so I have been doing exactly what I am supposed to do. When I'm hungry, I just drink more Water and deal with it. Just curious if it was normal or not. I made a typo in my original post. I meant to say "I AM able to get down my 80oz of fluids per day (including 3 Proteindrinks for 75g of protein)."
