"my sleep doctor prescribed this for me (i have sleep apnea) because i kept waking up at the slightest noise or movement from my husband. i take 100 mg before going to sleep and i can say it has changed my life for the better.  i can sleep for a solid 7 to 8 hours with little drowsiness in the morning.  in addition, it has helped my depression symptoms, although it may also be the better quality of sleep i get."
