WHOOP sleep and recovery data
Daily measurements alongside dated personal observations from maritime work, crew change and the return home.
20% → 98% recovery
October 9 to October 10: main sleep increased from 7h 21m to 9h 28m, HRV from 17 to 42 ms, and resting heart rate fell from 85 to 60 bpm. Travel, workload, sleep opportunity and reported compound changes coincided.
4h 03m deep + REM
October 10 recorded 243 minutes of deep plus REM sleep, or 42.8% of sleep. A lower percentage than some short shipboard blocks can still represent substantially more minutes.
The vessel context and what felt useful
The September 29 retrospective singled out Cortexin and Bemitil after roughly 100 cumulative days at sea/work. A new hitch was reported in late October, including a B-300 experiment, cargo work and further sleep observations.

Daily measurements and context
Sleep totals below include every recorded main sleep and nap ending on that local calendar date. Recovery, HRV and resting heart rate come from the main-sleep cycle. A blank recovery value does not mean zero recovery.
Posts describe Cortexin as already stopped by late September; later comments about persistent effects are personal interpretations. Exact dose timing is not established. October posts also report manual sleep entry, missed naps, rough seas and a planned compound break while flying home.

Methods and coverage
The October 12-named export contains 31 physiological cycles, including 30 with sleep and recovery measurements, and 59 sleep episodes. The last sleep ends October 10. Sleep durations are taken from sleeps.csv; recovery measurements come from physiological_cycles.csv. The same sleep is not counted twice.
Episodes are assigned to their exported local wake date, using the recorded UTC−04 or UTC−05 offset without converting them to a single home timezone. These are calendar groupings, not rolling 24-hour totals. Deep plus REM percentage is the sum of those stage minutes divided by recorded sleep minutes for that day. Missing measurements remain missing.
Post dates are those displayed by X, which may differ from the date of the reported sleep or the vessel’s local date. Earlier September notes use previously transcribed, linked posts; later notes were reviewed in a targeted search. This is not a complete account archive. Some posted percentages differ from the export; both are retained without claiming an exact episode match.
WHOOP stages are device estimates. Changing schedules, workload, sleep pressure, multiple compounds and measurement gaps prevent causal attribution. A stated plan to stop compounds does not establish subsequent abstinence. Raw timestamps, journal answers, workout details and the original ZIP are not published.
Earlier September analysis · historical snapshot
The chart below preserves the September 27 export and its original cycle-start date convention. Its approximate exposure phases are participant-reported working boundaries, not verified dosing logs. It covers main sleep only and is not directly interchangeable with the updated wake-date totals above.
*Working exposure dates reported by the participant. Dots show available cycles; no interpolation across missing records. The September 27 cycle was still open, so day strain is missing.
