insomnia
"I have been taking Ambien for 2 years now for insomnia and trouble sleeping.  It does make you tired, but you also feel really good and happy.  I would take it and an hour later, not remember anything. Also, I would still wake up every hour. It helped me fall asleep, but not stay asleep.  Recently, I over dosed on Ambien.  That is what really woke me up.  This is not for me.  I have been prescribed Seroquel for my sleeping problems and this is wonderful. I have no more sleepwalking and I remember everything."
