insomnia
"I've been using and still will use zolpidem for the last 8 years. I tried belsomra "clean off zolpidem at least 20 hours.The belsomra at 15 mg made me yawn. That was what the Dr. recommended. Did not sleep at all. Next day I tried 20 mg. Ever hear of sleep paralysis? Well 20 mg I got sleepy. I was impressed. I started to dose off and the sleep paralysis started to hit me. I got up and made some coffee and I won't take them anymore.Google sleep paralysis and you'll find it is not pleasant to say the least. And they wanted $300.00 for 30. Ended up with 10 for free with a coupon. Got 8 1/2 left and will not use the anymore.Took it 4 hours ago.Zolpidem beats this belsomra by far. I rate belsomra in the negative 10. 
Merck, Thumbs down on this one...."
