Some thoughts, I make no claim as to their accuracy:
In my experience, drinking too much coffee can give me a headache that makes me even more useless than if I had no coffee, this is a relatively easy magnitude to reach without trying.
I find it helpful to take a week every now and then where I use no caffeine at all, to help prevent my system from developing a tolerance to caffeine.
There exist pills that release caffeine over an extended period, for example 6 hours.
If you ever have problems with headaches that correlate with something hydration-related like napping or drinking coffee, make sure to drink more water. Dehydration is a common cause of headaches.
Drinking more water is like turning off a computer and turning it back on again. Using the bathroom more could mean your body needed to drink more water all along; it does not necessarily indicate that you drank too much water.
