| Step 1: | Patient maintains a daily sleep diary for 1 to 2 weeks. Average total sleep time and sleep efficiency are computed from the information on the sleep diary*. |
| Step 2: | The time in bed window is set to match the average time in bed period calculated from the sleep diary, with a consistent bedtime and rise time each day. The patient is instructed not to nap during the day or to reduce nap duration to the extent possible. The patient continues to keep a sleep diary until the next visit. |
| Step 3: | The time in bed window is reduced by 30 minutes until sleep efficiency is >85%. If the patient does not feel sufficiently rested, the time in bed window is maintained. The patient continues to keep a sleep diary until the next visit. |
| Step 4: | Step 3 is repeated until sleep efficiency is above 85% and the patient is sleeping well and feels sufficiently rested. |
