My narcolepsy is bizarre. I have months where I sleep 14 hours, and still exhausted and always in a fog and exhausted. Even if I get the recommended 8 hours I am ALWAYS tired. Then I have insomnia for months and can't get to sleep on ambien, lunesta, restoril, you name it. I was just given xyrem but that first dosage does not put me to sleep. I wait 3 hours after I eat. I am beyond frustrated. When I do finally fall asleep I get only two hours at most. The second dose gives me 2 hours, and then I cannot get back to sleep. The dosage was increased, and no change. Did anyone have this problem at first, and should I stay with it?
