Okay, real talk: if you’ve drank a swimming pool’s worth of water and your headache is still pounding after four hours, it’s probably not just dehydration. You might have a full-blown migraine, tension headache, or a personal grudge from your own blood vessels.
Don’t be a hero. Take an over-the-counter painkiller like ibuprofen (it’s anti-inflammatory, which helps with that brain-shrinking business). But here’s a twist: excedrin works better for dehydration headaches because it contains caffeine, which constricts blood vessels and counteracts the swelling.
Yes, I just told you caffeine is bad, and now I’m saying it’s good. Welcome to headache logic—it’s a chaotic neutral alignment. Just use a small amount, or you’ll crash later and need a nap under your desk.
