Why do I prefer solid foods to liquids when I have the stomach flu?

I have the stomach flu and when I drank rice mixed with water - I almost wanted to throw up.

But eating salted crackers I was fine.

It makes me think that somehow my body can't digest liquids right now.

Maybe I have too much water in my body? It sounds weird but that's what it seems like.
