insomnia
"I was taking Belsomra (20 mg) for almost a year, and initially it worked great. I was falling asleep in a natural way without feeling I had taken a sleeping pill. After three or four months things started to change. I started feeling a bit depressed with some anxiety. What was really strange is that I would get lots of work related anxiety -- things started bugging me at work that normally would not. It's like small things at work bugged me far more than usual. I could not understand what changed. In addition, I was accumulating some depression and everything took more energy to do. Finally, I started suspecting Belsomra was the cause, so as soon as I stopped, all these symptoms simply evaporated! OMG, I finally can feel the sunshine!"
