Can anybody explain why I feel like crap after drinking about 5 cups of decaffeinated coffee (black, without milk/sugar) during a workday?

Orange juice is more acidic and less associated with stomach problems (but not unassociated).
The mechanisms are hard to trace, since there are so many chemicals involved and the actual production of stomach acid so complicated. But you know what the doctor will say when you tell them that it hurts when you go like that.
Five, 16oz cups is 80oz, and there's 33oz in a liter.
I'm not trying to disagree with you, just describing how I got my number, which is different than your reasonable implication.
You may also have a mild food sensitivity/allergy to coffee specifically. (Yes, testing for food sensitivity is somewhat problematic, and often indicates the presence of intestinal permeability.)
The argument I got from a chemist once was something like "Yes, but they take all the toxic chemicals out of the beans after processing". Yikes.
Now that I think of it, I do feel bad one or two days after I stop drinking cola.
Perhaps it is the caffeine but it's acting in a different way, more like an addiction.
