My surgery was on June 26, 2015. Today is now day 4 post op. I have felt hungry. But that was when I was not taking in enough liquids. I started reading my book again. So 1 hour of waking up drink protein shake. Then water every 15 min sipping of course. Add sugar free jello, popsicle. Drink the shake on every hour. Then alternate with isopure. I recommend the coconut water isopure
