I Spent 90 Days Testing the DERYTHM Pro to See If I Could Finally Bin My CPAP — Here's Exactly What Happened.

An honest, day-by-day review from Wayne M., 58, Bendigo VIC.

I'll be straight with you: I only wrote this because my wife told me I had to.

Her exact words were, "Wayne, if this thing gave you your sleep back, you owe it to the next poor bloke lying awake at 3am to tell him."

So here it is. The whole 90 days — the good, the boring, and the bit where I nearly gave up. If you snore like a chainsaw, if you've got sleep apnoea, or if you've got a CPAP machine shoved in a cupboard that you can't stand wearing — this one's for you.

First, the part nobody warns you about

If you've worn a CPAP, you already know everything I'm about to say. And if you're about to start one — brace yourself.

It begins every single night with the ritual. You're lying there comfy, warm, half-watching something on your phone, and the second you feel yourself getting sleepy you realise you have to sit up, strap the mask on, clip the headgear, sort the hose — before you're allowed to drift off. Every night. Like putting your scuba gear on just to go to bed.

Then there's the mask itself. The red marks pressed into your cheeks and the bridge of your nose that are still there at breakfast. The hose that tugs at your face every time you roll over. The dry mouth at 2am, like you've been chewing sand. And if the seal slips even a bit — it whistles, or it blows air straight into your eyes.

Sue started calling it "the elephant trunk." Some nights the claustrophobia got the better of me and I'd wake at 3am and just rip the thing off my face — then lie there feeling guilty, because I knew I needed it. It wrecked her sleep as much as mine.

Nobody warns you about the rest of it, either. The cleaning — the tank, the hose, the mask, week after week, and the mould if you skip it. The distilled water. The replacement parts. Your wife lying next to a bloke wired up to a machine like a hospital patient.

But the thing that really got me was travel.

Sue and I used to love getting away — a weekend at the coast, a few nights in the caravan, driving up to see the grandkids. Suddenly every trip meant packing the machine like another suitcase, hunting for a power point close enough to the bed, and praying the caravan park didn't have a blackout. I left it at home on a weekend away once and didn't sleep a wink — every time I dozed off, an apnea slammed me back awake. Camping was off the table. The thought of a long-haul flight was a nightmare. It stops being a machine and starts being a leash.

That's where I was — knackered, fed up, and quietly dreading bed every night — when I first heard about DERYTHM Pro.

Why I almost didn't bother

I'll be honest — I thought it was rubbish.

A little device you put under your chin that "retrains" your throat? I'd been to sleep specialists. I'd tried the mouthguard. I'd tried sleeping on my side with a tennis ball sewn into my shirt (don't ask). I was the last bloke on earth who'd believe a gadget off the internet.

But I read how it actually works, and it was the first thing that made sense to me.

Turns out sleep apnoea isn't really an "air" problem — it's a muscle problem. The muscles at the back of your throat are supposed to hold your airway open while you sleep. After about 40, they start losing their tone, so they collapse when you're out cold. That's the snoring. That's the gasping. That's the whole thing.

A CPAP doesn't fix that — it just forces air past the collapse with a machine. The muscle stays weak forever, so you're strapped to the thing for life.

DERYTHM Pro goes after the actual cause. It uses something called NEMS — neuromuscular electrical stimulation, the same tech physios have used for decades to rebuild weak muscles — and sends gentle little pulses to those throat muscles while you sleep, to tone them back up so your airway holds itself open. On its own. No mask.

I figured 100 nights money-back meant the worst case was I'd waste a bit of time. So I ordered it.

"Is this even doing anything?"

Setting it up took about two minutes. It's tiny and light — it sits under your chin and honestly you forget it's there. Compared to the elephant trunk, it was heaven just to get into bed without gearing up like a scuba diver.

But I'll be honest with you, because I said I would: the first week and a bit, I didn't notice much. A couple of mornings felt a little sharper. Sue said the snoring was maybe a touch quieter. I nearly wrote it off.

This is the part I want you to hear: it is not an overnight miracle. It's retraining a muscle. That takes weeks — same as it would rebuilding any muscle in your body. If you're expecting Day 3 magic, you'll quit before it works.

The first morning I noticed

Around the four-week mark, I woke up before my alarm.

That doesn't sound like much. But I hadn't done it in years. I lay there for a second trying to work out what was different, and it was that I actually felt… rested. Not "survived the night." Rested.

Sue noticed before I did, really. She said I'd stopped doing the thing where I go quiet and then gasp. She'd been lying awake counting those gaps for years. She wasn't anymore.

The 3pm wall disappeared

The afternoon crash was the thing that had taken over my life. Every day around 3, I'd hit a wall — foggy, useless, reaching for a third coffee just to get through to knock-off.

By about week eight, it just… stopped showing up. I got through a whole Saturday building a deck with my son-in-law and didn't need a lie-down. I can't tell you the last time that was true.

I threw the CPAP out

At 90 days I went back for a follow-up sleep study, mostly because Sue made me. My numbers had come down to a fraction of what they were when I was diagnosed — without a mask, without a machine, just my own throat doing its job.

I came home, took the CPAP out of the cupboard, and put it in the bin. Sue took a photo of my face. I looked like a bloke who'd been let out of prison.

The honest cons (because you deserve them)

• It's not instant. If you can't stick with something for a few weeks, this isn't for you.
• You have to actually use it. Every night, like brushing your teeth. Skip it and you're just slowing yourself down.
• It's not a magic cure for everyone — but for a bloke like me, whose apnoea came from a collapsing throat, it did what three years of CPAP never did.

How DERYTHM Pro actually works

Where I'm at now

I sleep next to my wife again. I wake up before the alarm. I get through the day without the crash. And I'm not lying awake feeling guilty about a machine in the cupboard and what it might be doing to my heart.

We went away last month — three nights in the caravan, no power point hunt, no hard case to lug. I just threw the device in my toiletry bag and forgot about it.

If you're where I was — exhausted, fed up, dreading bed — do yourself a favour and at least look at how it works.
