"tried 10mg of belsomra last night for the first time and had an awful experience.    this drug causes very concerning effects.    i am a 55 year old engineer and have struggled with insomnia for 6 months.    i had been taking ambien  which i have become dependent on and want to get off so i tried belsomra.    i do not take any other drugs at all..    about 3 hours after taking the belsomra i finally fell asleep and had a very strange dream which i awoke from and experienced sleep paralysis.    it lasted 20 seconds or so and was terrifying.    i then fell asleep again,  did not dream and awoke 15 minutes later with the same paralysis experience.  i could not move my body but was i was awake.  i will never take this drug again."
