i have no idea but try wafer rolls

I like otter pops when I have a sore throat!

Toast, banana, sunflower seeds. Those are my too sick to eat go-tos.

I make broth with Better Than Bouillon.

I used to have to force feed myself when I wasn't hungry. Ramen was essential for priming the appetite. But not the bad stuff. Good stuff like Black Shin

Hang in!

Fasting can actually help recovery. But no matter if you eat what you can or nothing at all it is absolutely necessary to get enough water, salt, and potassium.

Something that might go down easy is plain canned beans, just make sure to drain and rinse them and maybe even soak them a little to minimize intestinal issues. Plain quinoa or lentils made in a rice cooker or pot with just water and salt could also be good.

Sometimes your hear about the BRAT diet. I'd recommend against it, it is very nutritionally poor so it will not give you much energy if you can only handle eating a little.

to eat something to keep my strength up

I wouldn't worry too much if you haven't eaten for a few days. I know of one instance where someone who was seriously obese went on a diet, and aside from vitamins and water, went over a year without eating. I've done over a week myself for the hell of it. Unless you're absolutely emaciated or have some sort of medical condition that creates a need for it, you can probably handle going for quite a while without food.

All that being said, this isn't to encourage doing it. Just that you're probably not creating any kind of dire health situation if you don't eat for a while.
