I have been using soy milk for one...I am wondering if im putting to much protein in one shake....each scoop has 20 grams and i only need 60. I was just trying to compound it in one drink because ill admit shakes are not my favorite thing. I see my doc tomorrow so Ill talk then...I might try a shake tonight with just one scoop of powder....I am just not looking forward to it...This is the bset ive felt since surgery.
