Given that Mr. M's total sleep time was 4.5 hours and only 56.3% efficient, be was assigned to restrict his time to sleep to 4.5 hours each night. Due to Mr. M's preference for being awake during the morning hours and because he already maintained a roughly consistent bedtime of 9:30 P.M. to 10:00 P.M, he decided on a 9:30 P.M bedtime and a 2:30 A.M wake time and we improved bis efficiency to 74%, with an average of 3.7 hours of total sleep time per night. Mr. M attempted to further increase his sleep efficiency based on these initial improvements. During the next weeks he increased time in bed to five hours. Tbe following week (after session 2), Mr. M's sleep efficiency improved to 83%, with an average of 4.2 hours of total sleep time per night. Over the next several weeks, Mr. M steadily increased his allotted sleep time, while targeting and maintaining sleep efficiency between 80-85%. By tbe end of the week 6, Mr. M bad increased his average sleep to 5 hours per night, with a minimum of 83 % efficiency.
