My coffee intake regularly creeps to the level of having a headache on withdrawal. Personally, my approach is this:
a) Never drink coffee on Saturdays. The routine change makes it easy to skip coffee one day.
b) If a coffee free Saturday induces a headache, skip coffee for a couple of days.
This is, for me, enough to lower the volume of coffee I drink, thus maintaining an acceptable level (by acceptable I don't mean healthy, I probably still consume way too much caffeine; I mean controllable)
