I just got a prescription for Ambien, and apparently I may make phone calls during my sleep and I won't remember doing so. Let me apologize in advance if I sleep-dial you. I hope I don't spill any of my deep dark secrets. Don't call me late at night and try to trick me either. I've also been warned of a side effect that, while rare, may occur: mood changes including aggressive behavior. So don't get mad at me if I hit one of you in a fit of rage. It's just my medication. You're not allowed to hit back.
