insomnia
"Ambien has been hit or miss for me. When it works it's bliss! 2 out of 3 days it doesn't work well. The CR is supposed to help me stay asleep but at best I get 4-6 hours of sleep. It's not the greatest sleep - I fall off and wake up frequently without feeling I've slept, but it's better than staring at the ceiling till dawn. It's expensive!"
