Personally I drink about 4-5 large cups of black coffee a day with no sugar or creamer at work.
On weekends it's a clear 0 cups. I rather drink something cold.
When I'm staying in the forest with my platoon I drink again 4 cups a day: 1 in the morning when I wake, 1 for breakfast, 1 for lunch and 1 for dinner.
At summer I like do make some frappes. It's really hard for me to find a good frappe where I live. There used to be an bar for "open minded people" called Kapp (Closet) that made the best frappe ever. Now the place is closed and I have this memory of the perfect creamie frappe stuck in my mind. A life long quest to find it again.
