I used to experience late day crashes and headaches quite frequently, and also chalked that up to excessive coffee intake. However, as someone who also spent little time in the kitchen (thinking I didn't have time for it), it turned out to be my haphazard style of intermittent fasting that was giving me the headaches. Now I spend no more than an hour or so each night making food with leftovers for lunch the following day, and my life has improved phenomenally. YMMV but I still drink plenty of coffee.
