"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."
