insomnia
"Took 10 mg of Belsomra and I started yeawning within 90 min. I went to bed and had nightmare that I was strangling all my pet birds. I woke up within two hours and felt unsteady, heart was racing and felt like I wanted to jump out of my skin. I felt irritable and nauseated too. Needless to stay I didn't lay down again and it took 12 hours for all the horrible side effect to go away. Maybe I had an allergic reaction to it, but nevertheless I am NEVER taking this devil's pill again. Back to the Lorazepam. Wish I could give Belsomra negative rating."
