Two beers last night, but — one week off smoking — the HRV didn't dip the way it used to. Bad sleep as a withdrawal side effect: insomnia, fragmented, rolling in bed.
Interpretation: The headline is the resilience, not the score. HRV 98ms sits inside the personal range (78–137) on a night with two beers and nicotine-withdrawal insomnia — before quitting, that same two-beer input reliably landed him in the 71–94ms trough (Jul 8: 71, Jul 10: 94). The smoking cessation is already showing up as a faster-recovering nervous system. The cost is in the architecture and the resting HR: 2 wake-ups (High vs the 0–1 reference), light sleep 60% (high — the "rolling in bed" is real), and RHR 54 bpm, the highest reading in the last eight logged nights (recent band 47–50). That is sympathetic withdrawal stress — the body idling a notch higher while it learns to sleep without nicotine. Deep 27% and REM 13% are both healthy, so the sleep that happened was decent; it just kept getting interrupted. This is textbook early withdrawal: it peaks around weeks 1–2 and settles by ~3–4. Nothing here needs a fix — it needs patience.
