I am the same, except for the lightheadedness. I feel hunger, I’m good about fluids, etc. And I still can’t feel that “switch” (I’m 12 days post-op). I’ve heard so many stories about people being able to eat only a tablespoon at a time, but I have no problem with a half a cup. I’m still consuming less than 1000 cals/day so definitely losing, but it’s a little disappointing.
