insomnia
"I have had insomnia for about 7 years.  I took temazepam (Restoril) for about 3 years, but it eventually quit working entirely so I started taking 10 mg of zolpidem nightly about 4 months ago.  It is very good at helping me to go to sleep quickly and I stay asleep about 6 hours but not much longer. I haven't felt any drowsiness the next morning or had any headaches or other side effects.  I have learned a few things about zolpidem, though.  I cannot eat at all for at least 2 or 3 hours before taking it.  Also, I need to go to bed within 15 or 20 minutes after taking it or it doesn't work very well. Lastly, I learned that I can't eat chocolate for at least 5 or 6 hours before taking it because of chocolate's high caffeine content."
