What's the difference between getting used to it and getting tired of it? For example, if you are tired of eating, you are used to eating.

If you are tired of eating, then you don't want to eat any more;

I'm used to eating, just like I go back to cook noodles and eat spinach at night. I never thought about buying other dishes and eating them in other ways. I went to the supermarket, went directly to the place where spinach was sold, took it and left. When I got home, I cooked noodles naturally. Once my roommate asked, are you tired of eating every day? I said, I am used to it; One day, a friend treated me and changed my diet. It feels strange.
