Suvorexant
"Have suffered with insomnia for years. Tried many medications with Zolpidem  ER (Generic Ambien ER) 12.5 the only one that helped. Even then, still was not getting great results at times.  Tried 10 mg of Belsomra, hoping for a better result. This was one of the worst nights I have ever had in my life.  Was wide awake until 4:30, followed by horrible, segmented, almost hallucinogenic dreams. After my alarm woke me, I was in the strangest state of mind, where I had to make myself speak. I finally told my husband, I'm sorry, I've got plenty of conversation in my head, but I have to MAKE myself speak.  I was afraid to drive after this, and had my son drive me. This condition eventually got better. One dose. Never again."
