>Headache pain often appears along with other signs and symptoms of dehydration, including darker-than-usual pee, dry mouth and fatigue

none of these symptoms are true for me.

"often" and "always" are two different words that mean two different things

		Yes, but hydration isn’t really a problem for me. I’m a bit of a water purification nerd, I collect water from a natural waterfall, run it through multiple stages of purification, and then start convincing myself it has some magical properties. I don’t drink soda or caffeine, I mostly just drink water.
