So I was sleeved 2 days ago, I was told to only drink whey protein isolate however I can’t seem to tolerate it at all. The thickness, smell , taste everything just makes me want to throw up. Most of the powdered ones do. Did anyone’s surgeon have a problem with them substituting for ready made protein shakes? I tolerate premier protein very well.

The surgery often changes our tastebuds & sense of smell making it difficult to tolerate certain foods, flavours & textures. I found the shakes awful - super sweet & grainy. I’d force myself to have one in the morning which I’d dilute & then had soup for the rest of the day. Bone broth is a better choice but I found them very salty so I ate cream soups.

Try a plant based protein powder instead of the whey. If you struggle with whey powder you’ll likely struggle with whey based pre made shakes too. Try making your own yoghurt drink smoothie by blending Greek yoghurt with milk to a thin consistency. Add some unsweetened powdered flavours if you need.

Check with your dietician &/or surgeon be sure though.

I felt the same about most of the shakes at first (although I liked them BEFORE surgery). I pretty much lived on Unjury's chicken broth-flavored protein powders (and they are whey protein isolate). They were savory and thinner than the standard shakes (although you can always add more water to a too-thick shake)
