Ambien may impair your thinking or reactions. You may still feel sleepy the morning after taking this medicine, especially if you are a woman. Wait until you are fully awake before you drive, operate machinery, pilot an airplane, or do anything that requires you to be awake and alert. Amnesia is common if you do not get a full 7-8 hours of sleep after taking Ambien.
I would also add this:
Since the above paragraph suggests you may have impaired judgment, you may not be alert, and you may experience amnesia if you wake during the expected 7-8 hours of sleep,
stay off the freaking phone while you are under the effects of Ambien.
Specifically, do not talk for three hours to someone with whom you've especially decided not to define a relationship.
Your lack of judgment will remove all filters of sensibility.
You will say more than any self-respecting girl would say.
And you will not remember.
(If you are lucky, he will be gracious to tell you what you said and carefully help you step off the ledge of freaking out.)
But seriously. Just. Don't.
