If you don’t want to do math or stare at your toilet bowl, use the “Sip and Listen” method. Keep a reusable bottle on your desk. Take a sip every time someone asks you a boring question at work. That’s roughly 10-15 sips per hour, which magically hits your target by 5 PM. If you forget, your body will literally yell at you via a dry mouth, a headache, or a sudden desire to eat a salt lick.
And remember: you don’t need to micro-manage water. Your ancestors didn’t die of dehydration because they forgot to hit their 64-ounce goal—they drank when they found a stream. You’re smarter than a caveman. Probably. So grab a glass, toast your own hydration, and stop worrying. You’re doing fine.
Unless your pee is orange. Then please, for the love of all things liquid, drink something.
