Warning: Harry Potter is crack! Millions have suffered from Harry Potter addiction before me, but now I've fallen prey too. So I'm here to warn you, children, if you've somehow managed to remain free of its influence up to now, do not touch, smell, or even look too closely at any Harry Potter books or the words may leap into your eyes and infect your brain.
Symptoms of Harry Potter addiction include but are not limited to:
--> An inability to concentrate on anything not related to Hogwarts, the Ministry of Magic, character arcana, or minute clues spread over 6 novels. In general, sufferers are prone to "magical thinking" and may refuse to go to work, eat, or even accept that "none of it is real." Once at work, they often spend hours combing through fan sites and repeatedly checking the current date to verify the ETA for "Harry Potter and the Half-Blood Prince" (2 days, 13 hours, 50 minutes, 30 seconds).
--> Waving your pencil like a wand, trying to make your car fly, and seriously considering what position you are best suited to play on your house Quidditch team, which may result in attempts to actually play Quidditch, which may result in death. Warning: a broom can NOT fly, even and especially when one leaps off a rooftop astride one.
--> An intensely irritating weeping rash between the toes and around the heel of the foot that is resistant to all forms of OTC treatment (Although I haven't been able to determine conclusively that this is Potter induced... could be poison ivy.)
Suffers can be recognized by their glassy eyes, dazed expression, and incoherent speech. If they respond to questions by starting "Well, Dumbledore says..." or "My life is a lot like Sirius' in PoA" then they should be immediately diagnosed with the affliction.
Unfortunately, no cures have been established at this time, although symptoms do seem to be relieved by periods of unconsciousness (sleep, drug induced torpor, or coma) and vigorous shaking (either of the victim directly or by earth quake). One can only expect for this epidemic to become worse with the release of book 6, "Harry Potter and the Half-Blood Prince", in only 2 days, 13 hours, 47 minutes and counting, or movie 4, "Harry Potter and the Goblet of Fire" which doesn't come out, alas, until November 2005.

I’ve been an addict for years.
