What side effects doesn’t Ambien cause?

We used to think the rare and troubling four-hour erection was about as weird as it got in the world of prescription-drug side effects. But then came Ambien, the sleeping pill that has been found (in rare cases) to cause people to drive without realizing it and/or “unlock a primitive desire to eat,” according to The New York Times. As with the sleeping drivers, patients who have this Ambien related-eating disorder apparently don’t remember anything about their nighttime snacks—they are usually tipped off by the candy wrappers all over the house or the crumbs in the bed.
