Unusual: I can't imagine what is in your vitamin that would be causing a withdrawal headache... Is there caffeine or something in it? Severe headache particularly "worst ever" headaches need to be evaluated..

Not the vitamins: Since multivitamins are usually harmless as well as a waste of money, maybe you have trained yourself to get a headache when you do not take them. Stay off vitamins for a while, and see if you adjust and headaches stop.
