Insomnia
"Drowsiness but no sleep, so much worse than the Ambien and Lunesta that at least work a little.  Finally fell asleep at 6am, woke three hours later, felt like death all day.  Dizzy, drowsy, poor appetite, felt like my body was made of lead.  I&#039;m often low energy but this was scary.  Took for one night, would rather stay awake all night than do it againz"
