Our 16-year-old high school junior strug

Answer

I'll read the relevant sleep-coaching cards before answering, so the plan is grounded in the actual fork logic for teens.

This is **circadian schedule mismatch (Delayed Sleep-Wake Phase)**, not a discipline problem and not classic onset insomnia. The signature your son shows is the textbook one, and that's good news — it means the right move is to work *with* his biology, not against it. Here's the read:

##1. Why this is a clock sitting late, not a habit problem

A delayed circadian clock and ordinary onset insomnia look the same at 10:30 PM (lying awake), but everything after that is opposite:

| Test | Onset insomnia | Your son's pattern | Schedule mismatch (DSPD) |
|---|---|---|---|
| Sleepy at the hour you want? | Variable / anxious | **Not at 10:30** | Not until ~1:00 AM |
| Asleep at a stable later hour? | Inconsistent | **1:30–2:00 AM, reliably** | Yes |
| Sleeps late when nothing forces a wake? | Fragmented | **12:30 PM weekends** | Yes |
| Worse when you push bedtime earlier? | A little | **5 h on school nights, wrecked** | Yes |
| Screens locked away at 10 PM helps? | Sometimes | **No — still 3 h awake** | No |

Puberty pushes the biological clock later; forcing a 16-year-old into a 10:30 PM lights-out is asking his brain to fall asleep before it has made melatonin. The dad is seeing the *behaviour* (lying awake) and reading "not trying"; the actual cause is the clock sitting2–3 hours late.

## 2. Tonight's 2–3 moves

**(a) Lights-out tracks sleepiness, not the clock.** For the next 2–3 weeks, the rule is *go to bed when he is genuinely sleepy*, not at 10:30. That likely means a12:30–1:00 AM lights-out at first. The point is to stop training his brain that bed = the place you fail to sleep. A fixed *wake* time matters more than a fixed bedtime at this stage (`references/hygiene.md` line 1, `references/cant-sleep.md` line 1).

**(b) Stimulus control + no clock-watching.** Bed is for sleep only. Phone out of the room (not just locked — out). Clock face turned away; minutes on a display become a scoreboard for the threat system (`references/insomnia-model.md` Catastrophising section). If he is still wide awake after roughly 20 minutes in bed, get up, sit somewhere dim, do something calm, return when sleepy — the classical get-up-if-awake rule (`references/cant-sleep.md` line 2). No bright screens, meals, or workouts at 2 AM (`references/cant-sleep.md` line 6).

**(c) Morning bright light, every day.** Within ~30 minutes of his fixed wake time, get **outdoor** daylight for 20–30 minutes (a walk to school, breakfast on the porch — even on a cloudy day outdoor light is ~10× brighter than indoors). This is the lever that phase-advances the clock. Pair with dim lights in the last hour before sleep (`references/hygiene.md` lines 2–3).

## 3. Weekly anchor (the sentence to hold)

> **Wake time does not negotiate — school days and weekends within about an hour of each other — and the first thing after wake is outdoor light.**

The wake time is what the light, the caffeine cutoff, and the sleep-drive side all hang off (`references/hygiene.md` line 1; `references/jet-lag.md` line 9). Weekend catch-up should stay within ~1 hour of the weekday wake, per AASM adolescent guidance (`references/life-stages.md` Adolescents). His current 12:30 PM weekend wake is the part pulling Monday back to square one — that is the "circular jet lag" the question described. If a 6:45 alarm is too brutal, the *negotiated* move is a fixed7:30–8:00 wake every day; pushing the school wake later is a system conversation (AASM position: middle/high school start08:30 or later) — a fair thing to raise at the next parent–teacher contact, not a household fight to win.

If you'd like, I can set a single daily wake-time reminder after you confirm the IANA timezone (e.g. `America/Los_Angeles`, `Europe/London`, `Asia/Shanghai`) and the wake hour you want to hold — anchor first, reminder second.

## 4. When to bring him to an adolescent sleep clinician — and the melatonin line

**See a clinician** if, after 2–3 weeks of consistent wake-time + morning light + lights-out on sleepiness, the school-night sleep window is still under 6 hours, or if the gap between his free-day and school-day wake stays wider than ~2 hours, or if there is any sign of witnessed pauses, gasping, very loud snoring, or unsafe daytime sleepiness. A clinician (paediatric sleep medicine or an adolescent-medicine physician) is the right person to evaluate DSPD formally, screen for the ADHD / anxiety overlap that often travels with it (`references/life-stages.md` ADHD / anxiety), and decide on **timed** morning bright-light therapy or low-dose melatonin — both are clinician tools here, not household ones. The clinician also rules out anything else before anyone names the clock.

**On melatonin: do not pick a dose yourself.** Even "small" amounts are part of a timed phase-advance protocol with a specific schedule relative to his dim-light melatonin onset — the prescriber or pharmacist decides the timing and the milligrams (`references/jet-lag.md` line 7 / `references/life-stages.md` line 2). Off-the-shelf gummies without a clinician in the loop are how families end up with groggy7:55 AM teens who still can't fall asleep at 10:30.

**ed flags I'm not seeing here** (breathing pauses, chest pain with blood, falling asleep at the wheel) — none of those were mentioned, so this stays a sleep-coaching plan; if any of those show up later, that goes straight to your family doctor.

Source cards opened: `references/insomnia-model.md`, `references/life-stages.md`, `references/hygiene.md`, `references/cant-sleep.md`, `references/jet-lag.md` (phase-advance logic applied to a fixed late clock). Hand off: weekly anchor + tonight's moves are yours; the melatonin timing, any dose, the formal DSPD label, and screening for ADHD/anxiety overlap are the clinician's.
