Record One Night From Lying Down to the Next Observable Boundary
Feeling tired, lying down, and later noticing that you are still awake are three personal observations, not an explanation. This guide records one dated night only. The card begins with the first observable lying-down action, such as getting into bed or settling in the place already chosen for the night. It then keeps only times you notice naturally, visible light, noticeable sound, device or entertainment facts, any time you stand up or resume an activity, any later return to the lying-down place, and the next observable boundary. Do not set repeated checks or reconstruct an unobserved interval. The card closes when there is no later observation to record or when the fixed morning boundary arrives. The finished sequence does not answer why, define a personal rule, or promise what another night will look like.
Set the date and first lying-down boundary
Write the date, local time zone, the first time you physically lay down in the place chosen for the night, and the observable action that marks it. Copy a clock time only if you already saw one; otherwise place the action between two known events. Record the next fixed morning commitment as a boundary without redesigning it. The card starts at this first lying-down action, not at the end of work or the first tiredness note. If you later get up and lie down again, keep each action in order rather than replacing the first one.
Mark the first tiredness observation in ordinary words
Record the first moment you remember noticing tiredness. Copy a visible clock time if you already saw one; otherwise place it between two known events. Use your own plain description, such as heavy eyes, slower reading, a pause before continuing, or simply the word tired. These are personal observations, not measurements and not explanations. Do not add a severity scale, compare yourself with another person, or reconstruct an earlier moment because it seems more logical later. Also note the activity in progress and whether it had a required finish, a chosen stopping point, or no stated end. Unknown remains an acceptable value.
Trace every activity that continued afterward
From the first observation, list activities in order until the evening closed. Give each an approximate start and stop, and identify whether it was required, shared, already planned, or freely continued. Entertainment should be named by the actual format or item rather than by a judgement about its value. If a device report is already enabled, it may confirm an application or pickup time, but the card does not require a platform and the report cannot explain the evening. Mark switches between activities, interruptions, and unfinished items. Do not call any interval wasted, productive, excessive, or successful; the purpose is a readable route.
Record only naturally noticed moments after lying down
After the first lying-down action, write a time only when you notice it without creating a new checking routine. At each naturally noticed moment, record your plain words, visible light sources, recurring or one-off sounds, and any device or media already in use. If you stand up, name the observable action and its approximate time; if you later lie down again, record that return separately. Keep navigation light, urgent contact access, shared-room agreements and ordinary safety unchanged. An interval with no observation remains unobserved rather than being filled from memory.
Add the last food and drink as timing facts
Write the actual item name, the amount only when it can be copied from a package, menu, cup, receipt, or known household measure, and the time it ended. Include later drinks separately. Do not estimate ingredients, stimulant content, calories, or a personal limit when the source does not provide them. The entry exists to place food and drink on the same timeline as activities, not to claim that either produced what happened. If the exact item, amount, or time is missing, mark that field unknown. Do not recommend adding, removing, or replacing anything while building the first record.
Close at the next observable boundary
The closing boundary is the last event you can directly place: a later lying-down action followed by no further observation, the first planned morning action, or another clearly recorded stop. Write which boundary applies and list missing or conflicting times in an unknown box. Do not assign a hidden time to an unobserved interval and do not turn the length between observations into a score. Finish with one sentence that names the first lying-down action, any naturally noticed awake moment or resumed activity, and the closing boundary. Then stop; another night requires a new card.
Common questions
Should I keep checking the clock after I lie down?
No. Record only a time you notice naturally; do not create repeated checks for the card.
What if I get up and do something else?
Record the get-up, the ordinary activity, its known end and any later return to the lying-down place in order.
Does the card explain why I stayed awake?
No. It records one bounded sequence and leaves the reason unanswered.
