"took 50mg to help me sleep. woke up after about 4 hours of sleep. heartbeat fast and thumping, thinking about anything and everything. couldn&#039;t go back to sleep for a couple of hours. the day after i felt amped, jittery and like i was in a fog. took for two nights, don&#039;t plan on taking again. need some sleep. this drug may work well for you, it&#039;s just not for me. i recalled trying this medication a few years ago, had the same results then."
