insomnia
"I'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."
