I think it was a 1 time thing...thank God.

I've been sleeping so well since I started the Ambien...it's seriously amazing! And yesterday, I made it through the day, including a 5-hour shift at work (and I work with kids -- yesterday it was babies under 2) without coffee. Yeah, by 4:00 I was exhausted and ended up taking a nap...but still. That's huge for me!
