Anyone else eating the same foods over and over because it's the only thing that works?

Most says I have two small sausage burritos for breakfast with sweet tea, a turkey sandwhich from subway with all the veggies for lunch and IF I can eat dinner it's a few bites of whatever I cooked with a banana and a handle full of nuts. Once a week we go out to logans and I get grilled shrimp a salad and some other veggies 😅 aside from my morning tea I can only drink ice cold water
