I am the same way! I am so tired of sweet things but have no problem with crystal lite and water! My nutritionist called to check on me the day after I came home and I told her how hard it was for me to drink sweet things and she said that I could have cream of chicken soup mixed with skim milk, so it becomes very thin, and then put it all in a blender with ricotta cheese and then strain it really well so there are no chunks and then warm it up on the stovetop. That has changed everything for me! It doesn’t have as much protein as a protein shake but it’s better than not getting any protein! She also told me about Gatorade protein which has 10 grams of protein per bottle. I haven’t tried them yet but she said they aren’t as sweet as protein shakes so I may be able to handle those.
