    Yes, it can. And paradoxically so can cutting off your caffeine after a long period of time. I have given myself a head ache from drinking more than a couple of my double short americanos in a day and during my quarterly "cleanse" the first two days I go without caffeine I have really bad headaches.

    Yes, it's a diuretic, which means it dehydrates you and thus leads to headaches.
