I don't know what's wrong with me. When I read the two definitions, I see the same information. I guess I'm just dim...

But I have to tell you all something that came up with my doctor, as she was writing a prescription for Ambien: "the first question to ask when someone complains about insomnia is, 'are you in bed?' because many times that's the big problem." My guess, based on nothing beyond my own blissful ignorance, is that the "Ambien Driving" thing is related to that. People who take Ambien without bothering about going to bed.

On another bulletin board, I read a whole thread about people taking Ambien and staying up, on purpose, because they felt "trippy." Since all the people I've seen interviewed who said they had experienced it were college age, I'm wondering if the problem might be, you know, self-inflicted?
