If the headache is from listening to Kingdumb maladies, now might be a good time to pitch them. Frequently, you can get one from "bad" music, or even Christmas decorations, if you have been programmed to hate those things enough (it's the being a witless, not the decorations or music, that causes the headache).
If your headache is independent of the witlesses, you might simply need more sleep. I would definitely check your food--if you find anything with monosodium glutamate, hydrolyzed proteins, autolyzed yeast, yeast nutrients or yeast extract, sodium or calcium caseinate, textured protein, or gelatin, that might be causing the headache. Hidden sources of MSG could include natural flavors, spices, broth, stock, and other flavored items (this is most likely with meat or cheese flavors than with fruit flavors). Hydrolyzed starch may or may not also have glutamate, as may modified starch or a host of other things (if there was any protein with the starch when it was hydrolyzed, that protein would contain the glutamate). Try reducing or eliminating these items (as well as aspartame) and see if your headaches are less severe or frequent.
And, if you take magnesium, it might reduce or eliminate your problem. That stuff works best with tension headaches (and might reduce a glutamate or aspartame headache), but it will do some good too with migraines and cluster headaches. Taking magnesium regularly might also reduce the tension headaches, and keep you from getting as many. Plus, it is much safer than pain killers, which you may still take if you still get a headache and magnesium and/or a nap doesn't clear it up.
