As coffee is 98% water, you are basically drinking water when you are having coffee!
So feel free to add coffee to your daily water consumption. Especially if you can drink it black, which is the best way to consume coffee in my opinion, though it is an acquired taste for many.
I was a "sugar and cream" coffee drinker for decades and then a few years back, I decided to cut out those empty calories and I forced myself to drink my coffee black. It took about 2-3 months to get used to it but now I like the taste of coffee so much that I'll never go back to sugar and cream. I even find myself ordering dark roasts and exotic blends as I can actually appreciate the flavors now.
I keep hearing that coffee (caffeine) is a diuretic but there is no science backing that up whatsoever. So feel free to add coffee to your water consumption totals.

Your body will spend a portion of the night reclaiming the water the coffee cost you, at no addition to your bladder. It just might be enough to let you sleep later, maybe even all night.
