insomnia
"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'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 "5", 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."
