"i&#039;ve been taking restoril for over a year.  at first i could sleep all night but now i am waking up after 4 to 6 hours, sometimes i can fall back to sleep but usually not.  i take it 30 to 60 minutes before i want to sleep and sometimes am still awake 2 hours later.  even though now i am averaging 4 to 6 hours of sleep it is so much better than 2 to 2.5, which was all i was getting before."
