@tillianisafox I drink (what my coffeemaker says is) 10 cups of coffee, every morning.
Don't look at me like that, it's a big mug. I didn't make the mug, I just drink coffee out of it. And I can't pour perfectly good coffee down the drain, that would be wasteful.
After my coffee, I'm wide awake and ready to deal with work, and by the time I'm ready for bed the caffeine is all gone. And my doctor says I'm in great shape. But, yeah, does complain about the coffee.
