Thanks! It was pretty terrifying, even if the Levaquin was compounding it a lot. When you get the drug, you get a 15-page printout of all the nasty side effects, ranging from the usual (nausea, diarrhea) to the unpleasant (tendonitis, hypoglycemia) to the horrible (CNS effects like insomnia, dizziness, irritability, and anxiety).

I'm never taking it again. I can't call it an allergy, because it's not a true hypersensitivity reaction (anaphylaxis, hives), but we don't have a word for "drug you had a really bad non-allergic reaction to." (Yeah, I'm sort of picky about that. I've heard "I'm allergic to $DRUG" so many times, and when I ask, "what happened when you took it?" they answer, "it made my stomach hurt." :P )
