Record sleep timing, waking, and daytime alertness in the morning. Estimate what you remember; there is no need to watch the clock overnight.
The interactive diary needs JavaScript. You can still use the NHLBI printable sleep diary.
Record the morning after
Use the date you woke up, including after daytime sleep.
