"i was hoping this would be a better long term sleep therapy than ambien (belsomra studies reported that was the case), so i gave it a try.  i took 15mg at the same time i would have taken my ambien.  it certainly didn&#039;t work as well as ambien when it came to falling asleep... it took 30-40 minutes before becoming sleepy enough to fall asleep.  though i slept pretty well for about 8 hrs, and would have otherwise rated this medication an overall &quot;5&quot;, i awoke with the worst anxiety that i have ever experienced. i felt like climbing the walls!  it was so physically uncomfortable that i had to just get up and bag the idea of sleeping in on a saturday morning.  three hrs after waking, the anxiety subsided enough that i was able to sit and relax."
