"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"
