insomnia
"Ambien CR was prescribed to me for long term use after I was only able to get a 3 hours of sleep per night due to insomnia. It did help me get to sleep (took effect within 30 minutes on an empty stomach) and stay asleep. However, it also makes things seem 3D that aren't (like text on a computer screen), and gives an overall "trippy" feeling. Ambien CR also has a rather strong hangover effect that can last awhile (up to 12 hours from the time it was taken.)
