insomnia
"Took ambien with no problems. Doctor wanted me to come off ambien and try Belsomra. He gave me samples. Took a 10mg dose and it didn't help me fall asleep or stay asleep. Up all night. Then- the weird nightmares. I had hours of vivid nightmarish dreams. Not good. Woke up exhausted. Why would anyone take this medication if it's going to give you nightmares? I'm already an insomniac. I don't need nightmares and hallucinations too. Going back to ambien."
