In our general medicine clinic, a 42-year-old woman named Tina says that for the last few months, she gets these “attacks” where all of a sudden she gets dizzy. She can’t stand up straight, and sometimes she hears a buzzing or high-pitched sort of noise. She says that she sort of staggers around and has to eat a candy bar. Once she has some sugar, in about a half of an hour, she starts to feel better.
