I'm in a similar boat, those headaches won't go away unless I try and sleep them off, but I can't alwasy stop to nap ya know. If I don't have a steady stream of coffee to sip on I am not the same person, I get irritated easily and I'm run down at odd times. My friends made up a poster as a joke. It has a picture of a monkey with the caption "me without coffee" and then a picture of Einstein and a caption "me with coffee". I have basically no mental capacity without coffee, which is bad since I'm a structural engineer
