insomnia
"I tried this medication for insomnia.  I had been taking Restoril 30 mg to help me sleep but it had stopped working as well. My doctor gave me samples of Belsomra to try and said I needed to start at 10 mg but it probably wouldn't work until I titrated up to 20 mg.  I had the worst night I've had in a long time after taking this. I became confused and upset.  I began crying and became dizzy and felt as though I couldn't breathe. I was terrified to go to sleep. I apparently did fall asleep at some point after lying awake trying to keep from going to sleep due to fear. I had horrible dreams.  Never taking this again. Worst night I can remember in a long long time. I've felt horrible all day, groggy, and nervous."
