I have three weeks of post-op liquid diet and am almost two weeks through it. I'm allowed to have unflavored Greek yogurt, skyr, and sugar-free fat-free puddings on my "liquid" diet and I find those help a lot. Also, warm savory things help—phở broth, miso soup, chicken broth. And the Fairlife nutrition shakes that taste exactly like chocolate milk seem to assuage my hunger.
It is better now than it was immediately post-op, for what it's worth.
