Your daily check-in
Keep food, movement, sleep, medicines and supplements in one personal protocol. A 90-second check-in records what you did and how you feel.
Record each intervention, its target, dose or amount, timing and what you actually did. Your next result then has the context it needs.
Multiple changes are not the problem. Unrecorded changes are.
Across 24 members, check-ins linked morning caffeine with 8 fewer minutes of deep and REM sleep a night. Logging together can reveal a pattern one person would miss.
Pick up where you are. Regular notes make your record useful; it does not need to be perfect.
