I cannot stay hydrated tonight

To much salt or spices in your system, heat, diabetes can cause that (hope it isn't that though), not hydrating enough while doing exercise?

Idk but I've got an orange juice craving. When I had nosebleeds as a child I was sometimes given an orange. Maybe crying is like bleeding.

Have you eaten bacon or something salty?

That happens to me if I have too much salt

Heat?
