insomnia
"I can see why this medication isn't for everyone. 
I have racing thoughts when I attempt to sleep. I take a 20mg Belsomra, make room dark and set myself up for sleep. 
My mind must calm because I wake up 5-9 hours later. 
This doesn't make you drowsy or euphoric. It helps me fall asleep like a normal person. 
Never will go back to benzos (for sleep) zopiclone, ezoplicone etc."
