As I'm prone to kidney stones, I have to drink plenty of fluids, about three or four liters a day.
And so I drink plenty of coffee. About four to five cups a day. Fresh brewed or instant. Doesn't matter. Those twelve or fourteen ounce cups. On the weekend, five to seven cups a day. Those fourteen or sixteen ounce jobs at either Dunkin' Donuts or at 7-11. I dislike Starbucks. I won't go there. It's way too bitter.
I also drink a lot of water about a liter and a half, thirty-four to forty-five ounces a day.
