I eat pretty much all that food, all the time! I'm not 3 weeks out though, so I'm sure it will be different for you. But I eat sushi, nigiri, miso soup, edamama, fresh tuna, rice, etc all the time. It's really healthy food, and I have absolutely no problem with rice getting stuck. I don't eat steak though, but that's because I dislike it, not because I've had any problem with it.
