insomnia
"I have worked rotating shifts for over the 30 years and I have never had enough sleep. So I asked my doctor if there was anything I could try. He suggested Ambien, 10 mg at bedtime. So for the last year I now wake up after 6 hours of rest, which nothing compared to years of restless nights tossing and turning over to look at a clock. Good sleep means a lot and is worth a pill every night."
