You may not be able to get in all your Protein and liquids at first, but you'll work up to it. You'll concentrate on liquids first and foremost. As far as shakes go, your tastes may change after surgery. I would not count on your favorite type staying your favorite. Personally, I keep chocolate, vanilla, and plain protein powders in the house to add to things like yogurt, smoothies, milk, etc... Also, don't buy oodles of food ahead of time. I wasted a ton on money on things I never used. I have baby food meat, dried milk, lots of broths, ready made protein shakes, and lots more than I'll never use. I had a relatively easy time with food and once I got to the puréed stage, I didn't really need anything too specialized. Good luck to you from a fellow planner!!
