I had horrible heacahes from ~16-19 years old... I never made the connection until a professor in college mentioned 'caffeine withdrawal headache', and it totally clicked. And I switched to decaf for the next 15 years. Totally paranoid about waitresses filling my coffee cup up with the wrong pot.

However, a couple of years ago, I noticed that I can actually drink caffeine without getting any withdrawal problems at all, making me think it was all in my head...
