The day started high, peaking at 216 mg/dL at midnight and staying above 180 until about 12:50 AM before settling into the 100s–140s for most of the morning and midday, with a quiet stretch in the low 90s around 11:30 AM–12:30 PM. The one low came in the late afternoon: glucose fell from 168 around 3:50 PM to 62 by 4:45 PM and bottomed out at 53 mg/dL around 5:05–5:10 PM, returning above 70 by about 5:35 PM (roughly 45 minutes below range). A rebound followed, with brief highs of 186–187 around 6:35 PM and a longer stretch above 180 from about 7:40 to 8:20 PM, peaking at 199. Activity for the day was light: 4,037 steps, 323 active calories, and about 7h 45m sedentary.
The night ending this morning was a solid one: Oura scored sleep at 87 with 7h 44m asleep in about 8h 50m in bed (efficiency 88%), including roughly 1h 16m of deep sleep and 1h 41m of REM, with an average HRV of 18 and a lowest heart rate of 79. That lines up well with the CPAP, which logged 8h 32m of mask time in a single session (9:29 PM–6:01 AM), the gap to Oura's asleep time being time spent awake in bed. AHI was a very low 0.4 (all obstructive) and the leak 95th percentile was 0.0 L/min against the 24 limit, and readiness came in at 89 with a recovery index contributor of 66.
