I've never taken an actual sleeping medication - I have been taking Amitriptylene though (have no clue how wrong that's spelled).
I used to wake up constantly throughout the night - along with it taking 2-3 hours for me to fall asleep. Mostly due to pain, I would wake up at least 2-3 times an hour. My husband sleeps like a rock so it never bothered him - but for me it was horrible, sleeping never rested me.
The Amitrip helped sooo much with that. I fall asleep within 10 minutes of going to bed, and only wake up a few times during the night.
The real test is how much you feel rested when you wake up. I agree with the above that your wife might not be getting very good sleep either.
