If you are unsure about your sleep-wake timing, frequency of your sleep-wake disturbances, or overall symptom duration/timing, the best first step is to perform a sleep study to observe your sleep-wake cycle. This is best accomplished by using a sleep diary to record sleep-wake history for 14 days. You or your sleep health provider can use this information to map out the next step.
