Reply #29: Ambien can help people with transient insomnia.

The major ADR that most people experience is the "morning-after" effect. Basically, the drug isn't cleared by morning and so they feel groggy. My personal thought is that many of the stranger effects of Ambien can be attributed to this. My theory is that people are having "micro-sleeps" when they're going about their business, which could account simultaneously for strange behavior as well as the lack of recall concerning events (as sleep onset induces a mild retrograde amnesia).
