insomnia
"My Dr wanted to change my prescription of ambien CR. And put me on belsomra. Didn't sleep for more than 10 minutes at a time, then couldn't tell if I was asleep or awake.  Probably the worst nights sleep I've ever not had.  On top of this, I also suffer from depression. If you do, DON'T take this drug. The next day all my work colleagues kept asking me why I was so sad.  I know you are supposed to take it for a few days.  I can't take that risk.  I'll just buy ambien if I have to.  I've been taking it for 10 plus years and have never had any side effects  just good night's sleep.  I can't believe how depressed I'm still feeling. "
