ADHD dx · On Vyvanse

"Diagnosed at 39. Two years on Vyvanse and still couldn't fall asleep before 1 AM. Tried every dose adjustment. The second wind kept arriving at 10 PM regardless. By day 12 it stopped. I was asleep by 11:30. Oura HRV went from 28 to 41 by day 30."

"I bought this for my husband after he was diagnosed at 44. For years I watched him doom-scroll until 2 AM and wake up destroyed. Week two — in bed before midnight for the first time in our 11-year marriage. Week four — waking before the alarm."

"Called myself a night owl my whole life. Found out at 38 it was ADHD — and that the night owl thing is a measurable biological delay. WHOOP deep sleep 11% → 22% over 30 days. The revenge bedtime procrastination cycle just stopped. Didn't even have to fight it."

Circadia — PDP FAQ Block (Shopify Preview)

Common questions

The three questions
every ADHD adult asks.

Answered at the same clinical standard as the protocol itself. No soft language. No deflection.

Does PM Drift contain melatonin?

Formulation

+

PM Drift contains zero exogenous melatonin. This is deliberate.

Standard sleep supplements use 5–10mg pharmacological doses of melatonin — which sedate without advancing circadian phase and suppress the body's own DLMO production over time. The goal of this protocol is to restore the body's capacity to generate melatonin on schedule, not to replace it.

PM Drift supports this through two upstream pathways: Tart Cherry Extract provides naturally occurring melatonin precursors that support the body's own pineal production, and Zinc supports the enzymatic conversion of serotonin to melatonin in the pineal gland. The formula also reduces the cortisol elevation that directly suppresses melatonin onset — using Ashwagandha KSM-66 and Lemon Balm — so natural DLMO can fire at the correct time.

Zero exogenous melatonin Tart Cherry precursors Pineal support via Zinc Cortisol wind-down via KSM-66

↻

The result is entrainment of the body's own clock — not substitution of its signal. The clock learns to run on time. It does not wait for the next dose.

Will there be dependency after 30 days?

Protocol design

+

Entrainment and substitution are not the same mechanism.

Dependency in sleep supplements comes from two mechanisms: GABA-A receptor downregulation — the mechanism behind benzodiazepine and z-drug dependency — and melatonin receptor desensitisation from chronic high doses. The Circadia Reset Protocol was designed to avoid both.

Every ingredient in PM Drift was selected on the entrainment principle: L-Glycine supports thermoregulation rather than sedation. Tart Cherry provides melatonin precursors rather than melatonin itself. Apigenin binds GABA-A receptors without suppressing the body's own GABA production — structurally distinct from compounds that cause receptor downregulation. Ashwagandha supports the cortisol decline that allows natural DLMO to fire on time.

The 30-day protocol provides consistent timing reinforcement until the master clock has rebuilt its own entrainment capacity. Then the protocol is complete.

No GABA-A downregulation No receptor desensitisation 30-day defined endpoint Apigenin — not benzodiazepine class

→

Circadia is a protocol with a finish line, not a supplement with an indefinite subscription. The goal is a biological clock that operates independently — not one that requires nightly intervention to maintain function.

Is it safe alongside Adderall or Vyvanse?

ADHD medication

+

The formulation was developed with ADHD pharmacological profiles in mind.

Neither AM Rise nor PM Drift contains compounds with known interactions with amphetamine-class stimulants at the doses provided. The ingredients operate on circadian, HPA axis, and GABAergic pathways — not dopaminergic pathways — which is the mechanism stimulant medications act on. This minimises interaction risk by design.

Ashwagandha KSM-66 has been studied specifically in ADHD populations and shows no contraindications with stimulant medication. L-Theanine is commonly combined with stimulant users to reduce overstimulation. PM Drift contains zero exogenous melatonin, which removes the most common interaction concern with ADHD stimulants and sleep compounds.

Consult a qualified healthcare provider before starting any supplement protocol if a hormone-sensitive condition or thyroid disorder is present, or if taking antidepressants or MAO inhibitors.

Circadia — PDP How It Works + Two Signals (Shopify Preview)

How It Works

A circadian routine
in 2 minutes a day.

Built specifically around the ADHD circadian delay

In adults with ADHD, the two timing signals that govern the 24-hour body clock are systematically disrupted — the morning cortisol signal fires too weakly, and the evening sleep signal fires too late. Circadia addresses both ends simultaneously.

Take AM Rise with the morning routine. Take PM Drift during the wind-down window. Pair with the personalised 4-week plan from quiz results. The consistency of the timing is the entrainment signal. The body learns to anticipate both windows the same way it anticipates sunrise.

Morning

AM Rise — within 30 minutes of waking Targets the Cortisol Awakening Response — the biological ignition signal that determines cognitive function and when sleep pressure builds that night.

Evening

PM Drift — 60 to 90 minutes before target sleep Targets the DLMO window — supporting the cortisol-melatonin transition, core body temperature reduction, and N3 sleep architecture. Zero exogenous melatonin.

No sleep journal. No 10-step routine. No rigid rules. Executive dysfunction makes complex sleep protocols fail by design. Two formulas. Two windows. Consistent timing. That is the full protocol.

Why This Works

Two signals.
One stable rhythm.

In adults with ADHD, both signals are systematically disrupted

Most sleep interventions focus only on the night. Circadian alignment is different — it is about correcting the start signal so mornings feel switched on, and protecting the stop signal so sleepiness arrives on time.

Standard sleep supplements address one signal, in one direction, at one end of the night. The ADHD body clock requires both signals to be recalibrated simultaneously — which is exactly what the AM + PM structure is designed to do.

Start Signal — AM

Cortisol Awakening Response

The sharp cortisol spike within 30 minutes of waking that anchors the biological day and determines when sleep pressure builds that night. In ADHD, this signal fires at reduced amplitude — producing morning fog and stimulant dependence.

Stop Signal — PM

Dim Light Melatonin Onset (DLMO)

The neurochemical event that initiates the shift from wakefulness to consolidated sleep. When DLMO is delayed, sleep latency extends and architecture fragments. In ADHD, DLMO averages 11:43 PM — 90 minutes later than a neurotypical clock.

↻

Standard interventions address neither signal at the source. The Circadia Reset Protocol was built specifically around this gap — targeting the ADHD circadian delay from both ends of the 24-hour cycle simultaneously.

How the 4-Week Circadian Program Works

Most sleep protocols track habits. This one tracks the biology.

Week 1

Set the anchors (stability first)

The focus is on establishing a stronger morning cortisol awakening response. The upstream biological event that determines when sleep pressure builds later that night. AM Rise is taken at a consistent time each morning to begin shifting the DLMO window earlier. Most respondents notice waking is less forced by Day 2. The morning signal begins calibrating before the evening changes become measurable in tracking data.

Week 2

Reduce the Interference

The focus is on targeting evening cortisol elevation. The primary reason melatonin onset runs late even when exhaustion is present. PM Drift supports the wind-down phase during the cortisol-melatonin transition window. This is where most users report their first consistently earlier sleep onset, typically between nights 10–14, as the DLMO signal begins shifting into its natural range.

Week 3

Consolidate the Architecture

The focus is on reducing WASO events. The nighttime wake-ups that signal circadian trough instability in the second half of the night begin resolving. As the AM and PM signals compound across three weeks, sleep cycles begin completing without interruption. This is the week the overnight wakeup pattern, which has been the primary disruption, begins clearing consistently.

Week 4

Stabilize the Rhythm

The focus is on locking in a self-sustaining 24-hour feedback loop between the morning cortisol signal and the evening DLMO window. By week 4, the protocol has done its job. Morning energy arrives on cue, evening wind-down begins without effort, and sleep timing holds consistent without requiring management. The protocol is complete. The 30-day entrainment window has closed. What follows is a clock that runs independently.
