An overnight sleep study was performed on this patient at the end of 02/07.  At that time, she reported that her sleep was better in the laboratories compared to home.  She slept for a total sleep time of 398 minutes out of 432 minutes in bed (sleep proficiency 92 percent).  She fell asleep in the middle of latency of less than 1 minute.  She woke up after sleep onset of 34 minutes.  She had stage I sleep that was some elevated at 28 percent of total sleep time, and stage I sleep is predominantly evident in the lateral portion of the night.  The remainders were stage II at 69 percent, stage III and IV at 3 percent of total sleep time.
