I had my surgery May 13 and have the same problem, both the milk products and anything with sugar substitutes make me feel horrible. :-( I have gotten some almond milk, but it doesn't have as much protein in it. And of course the whey protein powder I have is made of cow's milk. I am in Chile (I work here and had my surgery here), so it's not like I can just pop to the store for a different kind. They don't even focus on the protein for the post-op diet here, which I find a little odd. Of course, the protein powders they do have cost like 3 times as much as in the US, where they are already expensive, so that could be why.
