I took Ambien for a short time. I stopped taking it because, in my sleep, I got online and gave a friend of mine the cell phone number of the first cell phone I'd ever owned, ten years earlier.

It was really unsettling. I didn't even remember my old cell number when I was awake (I still don't). When my friend told me (online) that she had tried to call me (using the number I'd given to her) I was confused, then shocked. I had NO memory of getting up, getting online, and giving my friend my old number.

The whole thing was extremely creepy and I've never taken Ambien since.
