Clonazepam
"I have PTSD and have a lot of difficulty with falling asleep, staying asleep. One symptom is not reaching a deep sleep past REM, and having nightmares through-out the night, continually waking, panicked. I was prescribed a sleep med that made me some what relaxed, or I maybe only slept for four hours, and still having nightmares. This went on for months. I was prescribed Clonazepam and it has been a God-send. Not being able to sleep normally had a terrible affect on my daily life. I take it a few hours before bedtime, and when ready I lay down and sleep soundly, waking the next morning feeling relaxed, rejuvenated. I am able to return to a normal activities without the fatigue."
