Hungover

When I woke up this morning I swore never to drink again. Horrible hangover. Wait. Hold on. I didn't even drink yesterday! In fact, I was extremely prudent and worked all night on my seminar paper! Hmm. Is it possible to develop the same symptoms as hangovers when working very hard and focused? This is weird.
My head is spinning and feels extremely heavy. There can only be one reason for this: I'm becoming too intelligent. There's only so much room for brains in my head! I mean, where does all the knowledge I'm amassing and have been amassing for year? Some people seem to be able to handle that quite well. Like Homer Simpson. He forgot how to drive a car so he could learn to swim (or something like that, I forget the exact circumstances). I can't seem to be doing this. At least I still know how to drive. And swim. Do I have to learn to live with hangovers? And how do I tell 'intelligence hangovers' apart from real hangovers? All these questions.
