Hello and welcome. A few things I found helpful post op; Shot glasses. My docs suggestion for liquid was 1 oz every 15 minutes after the first day. A shot glass is one ounce, so you know exactly what you're getting and it feels like you're accomplishing something, when a 20 oz bottle seems insurmountable. Abdominal Binder: if they don't give you one, get one. It really keeps everything in place, which decreases your pain at home. For the first week of clear liquid only, I used (as did my hospital) Isopure Zero Carb Clear Protein. It has 40g per 20oz bottle, compared to Protein 2o's 15g/20oz. I did, and still do not, enjoy any premade protein shakes. I get flavored protein powder from Aldi ($14 for 19servings/30g protein each) and made my own with high protein milk and ice. They have chocolate and vanilla. Unflavored Protein clumps if you mix it with hot beverages/soup. So go warm only. That's all I can think of for now. Good luck to you both.
