Insomnia
"Silenor works very well keeping me asleep longer than usual.   I normally wake up 3-4 times a night without it.  But I have extreme dizziness and headaches the next day.  I think I&#039;ll go back on my Lunesta because I have trouble functioning the day after Silenor.  It is a great medicine but I&#039;m not sure if it&#039;s for me."
