Insomnia
"On rare occasions when it put me to sleep it gave me a steady stream of mini, vivid nightmares that had me awaken to a  depression.  Sometimes I&#039;d have the steady, mini vivid dreams lucidly, always conscious and knowing what side I was lying on, and then drag through the next day exhausted.  But most of the time no sleep nor vivid dreams; nada.  But the worst thing about Belsomra is its constellation of side effects: stiff muscle tone with unexpected contractions and coordination problems, crazy-bad depression, irritability, confusion and memory problems.  Beware."
