I had my revision June 21st, original R N Y in 2005. Just remind yourself it is to make sure your liver is smaller to make the surgery less complicated for you! If you haven't tried them yet, bariatric pal has awesome protein shots available. I love the orange. It's like conentrated Tang! 100 calories, 15 grams of protein. Other really good protein shakes that got me through it, Redcon1 Protein shakes are 0 grams of sugar 250 calories and 40 grams of protein. Also KaChava is a good powder shake with alot of protein and super foods in it. I still incorporate these in my diet post surgery and it definately helps. Hope your surgery goes well with no issues!
