I'm writing this because after three years of trying everything, this is the first thing that helped my crashes - and I wish someone had told me about it sooner.
I need you to read this carefully. All of it.
Not because I'm selling you a cure. Nobody has one, and anyone who tells you they do is lying to you. But because what I'm about to tell you is the thing I needed to hear in year one, and didn't hear until year three.
I've had long COVID with PEM for over three years. I've read the threads at 3 AM. I've tried the stacks. And I can tell you right now — I already know your story. Because I've lived it.
You're exhausted. Not regular tired — the kind where your body feels poured full of cement and a full night's sleep does nothing.
You've stopped making plans. Not because you don't want to go — because you never know what it will cost you. Maybe you've cancelled so many times that people stopped asking. Maybe you're terrified you've become the one who has to be managed.
Your brain doesn't work like it used to. The fog. The lost words. Reading the same page three times. You used to be sharp. Now you wonder where that person went.
And then the good day — you finally feel almost normal, so you fold the laundry, take the walk, see the friend. And 24 to 72 hours later the bill arrives. Poisoned. Flu-ish. Flat in a dark room for… days.
I know. I've been there. And I need you to understand something:
You are not lazy. You are not deconditioned. And this is not in your head. Something is physically wrong with how your body makes energy.





I don't write things like this. I barely post. But I keep thinking about the people who are where I was in year one.
Here's what most people — including most of the doctors I saw — don't understand about PEM:
It's not a tiredness problem. It's an energy problem.
Every time you go over your limit — and with PEM that limit can be a shower — your body can't cover the cost. Not that afternoon. A day or two later.
This isn't theoretical. This is what a crash is like from the inside:
→ Your body turns to cement. Arms, legs, head. Some days you can't lift it off the pillow.
→ Your brain shuts down. You can't find words. You can't finish a sentence. It feels like a concussion nobody can see.
→ You get the flu that never arrives. Sore throat, chills, that poisoned feeling — and no fever to show anyone.
→ Your income takes the hit. The one thing that helps is rest, and rest is the one thing the bills won't allow.
→ The people you love pay too. They cover the school run, the dinner, the plans you had to cancel again.
I'm telling you this not to scare you — you're already scared. I'm telling you because I spent two years being told I was anxious, or out of shape, and that I should ease back into exercise. So I pushed.
Pushing through is what made me worse.




I debated whether to include this part. It's uncomfortable. But I'd have given anything for someone to say it to me sooner — so I'm saying it now.
This is what happened to me, and what I've watched happen to a lot of people in the long COVID forums. It isn't a medical prognosis. Some people do slowly improve with time and strict pacing. But this is the pattern nobody warned me about.
-> Stage 1 — The "I'm Hardly Doing Anything" Phase
You have a decent day, so you do a little more. A walk. A work call. The laundry. Then you lose the next two days and can't work out why. You're barely doing anything — how can it be too much? You tell yourself next time will be different.
-> Stage 2 — The Crashes Get Longer
Two days in bed turns into five. The triggers get smaller: a conversation, a drive, a stressful email. You start cancelling things in advance. Your doctor says your bloodwork is fine and suggests building your activity back up gradually.
-> Stage 3 — The Baseline Drops
After one bad crash, you don't climb all the way back. What used to be a bad day is now a normal one. Stairs become a decision. You go part-time, or you stop. This is where I finally learned the word "pacing." Two years too late.
-> Stage 4 — Life Shrinks to One Room
Mostly housebound. Groceries by delivery. A stool in the shower. I've read the posts from people here, and they are not weak people. They're people who were told to push.
I'm not writing this to scare you. I'm writing it because nobody told me at Stage 1, and I found out at Stage 3.
Wherever you are, you're still reading. That means you're still looking for a way to stop this.
So was I.

Here's what finally made it make sense to me:
The root cause of the crash isn't your attitude. It isn't your fitness. It isn't even how much you rested last week — though that matters.
It's the power plants in your cells.
They're called mitochondria. They make the energy for everything your body does — your muscles, your heart, your brain. In 2024, researchers took muscle biopsies from long COVID patients with PEM, before and after exercise. They found that mitochondrial function was markedly reduced — and that it got worse after exertion.
Low output = no reserve.
No reserve = the crash.
That's it. That's the explanation I waited three years for.
And it's exactly why almost nothing I tried ever touched the crashes.

Antihistamines, beta blockers, salt — they help the symptoms they're built for. Heart rate. Histamine flares. They did nothing for my crashes.
Graded exercise and "just push through" — the most damaging advice I was given. With PEM, going past your limit is the trigger, not the treatment. In 2021 the UK's NICE guideline stopped recommending graded exercise therapy for ME/CFS for exactly that reason.
Stimulants and "energy" products — they lend you energy you don't have. You feel better, you do more, and the bill is bigger. In the forums we call it fake energy.
The supplement shoebox — I had more than 20 bottles and spent close to $200 a month. I took them all at once, so I never knew what was doing anything. Mostly, nothing was.
And pacing? Pacing is the one thing that ever protected me, and I still pace every single day. But pacing manages your limit. It doesn't raise it.
Every single one of these manages a symptom or manages the limit. None of them go near the thing that's actually short: the energy itself.
That was the piece I'd been missing.
I'll be honest with you — when a friend kept sending me studies about CoQ10, I rolled my eyes. Another supplement? I had a shoebox of them.
Then I read what CoQ10 actually does. It's a nutrient your body makes itself, and your mitochondria use it to turn food into energy. So I tried it on its own. One thing. Every day. Nothing else changed. Then I watched what happened over the next three months.
✓ Crashes getting shorter.
✓ Small things — folding laundry — no longer costing me the next day.
✓ My bad weeks a little less bad.
It did not cure me. I still have PEM. I still pace. Last month I had a rough week. But my crashes went from a week in bed to a couple of days — and if you have PEM, you know that is not small.
Here's what it is:
Origin8 Mitochondrial Support is one capsule a day of 200mg Brewed-CoQ10™ — CoQ10 fermented from yeast here in the USA. The same form your body makes itself.
Three ingredients: CoQ10, rice flour and a plant-based capsule. Every batch is third-party tested.
No oils. No fillers. No Polysorbate 80. No stimulants. Nothing that lends you energy you don't have.
You take it with a meal. That's the whole routine.
But here's what made me actually trust it:
They don't ask you to believe them.
You get up to 90 days to feel a difference. If you don't, you send one email and you don't pay. You don't even send the bottle back.
That isn't cure language. That's a company that knows it won't work for everyone, and has priced that in.
Over 150,000 bottles have been sold so far.
See What I Take Every Morning ➜In three years of this, I've watched myself and half the forums run the same loop:
Good day → do a bit more → crash → dark room → climb back → good day → do a bit more → crash harder.
Meanwhile the savings drain, the job slips, the relationships strain, and the baseline quietly drops.
I'm tired of watching it happen.
CoQ10 is the only thing I've tried that goes at the energy side of this instead of the symptoms.
It's one capsule. It's not a stimulant. You keep pacing exactly the way you do now. No protocol, no program, no pushing.
I can't promise it will work for you. There is a real trial where CoQ10 didn't beat placebo, and I've put it in the questions at the bottom of this page because you deserve to know. Some people feel nothing. But as someone who lost two years waiting for a doctor to offer me anything at all, I'm asking you:
Don't wait for permission to try one low-risk thing.
A good day shouldn't keep costing you the week after. And the longer the loop runs, the more it takes.
If you recognize yourself in anything I've written, take the next step. Not next month. Today — the 50% off ends in 12 hours.
It comes with the Only Pay If You Feel A Difference guarantee — so the only thing you're putting in is ten seconds a day.
See If Origin8 Is Right For You ➜
Before I spend money on anything now, I need to know I'm protected. Most of us are living on less than we used to. That's non-negotiable for me.
So I read the guarantee before I ordered a single bottle. It's the reason I'm comfortable telling you about this at all.
You have up to 90 days to test it.
The trial is 30, 60 or 90 days depending on the bundle you choose. I took the 90 — because CoQ10 builds up slowly, and they'd rather you give it the full run before you judge it.
If your crashes aren't any shorter… if a small task still costs you the next day… if you simply don't feel a difference…
You send one email. Full refund. No forms. No awkward questions. No sending the bottle back.
In three years and thousands of dollars of supplements, nobody else offered me that.
So let me be clear: the only real risk is another three months exactly like the last three.

I want to talk about something that doesn't come up enough in the threads.
The people at home.
PEM is never a solo illness — it takes your partner's evenings, your kids' weekends, and everybody's patience, including your own.
There were nights I was too wiped out to read my son one short picture book. My partner quietly stopped planning things. Nobody complained. That almost made it worse.
I felt like a burden in my own house. If you've felt that too, please hear this: you are not one. You're sick, and you're still here, and they know it.
Here's what I want you to understand:
Getting even part of your capacity back isn't only about you. It's about the people who've been rearranging their lives around a crash calendar none of you chose.
When my crashes got shorter, the first thing I noticed wasn't "I have more energy."
It was "You're up?"
It was finishing the whole picture book.
It was going outside twice in one week.
If it's hard to do one more thing for yourself — do it for the mornings with them. They never stopped being on your side.



One thing I love about this is how little it asks of me. When you're rationing energy by the spoonful, that matters.
Step 1: Take one capsule. That's 200mg.
Step 2: Take it with breakfast or lunch. CoQ10 is fat-soluble, so food helps your body absorb it.
Step 3: Keep pacing exactly as you do now, and change nothing else, so you can tell what's doing what.
That's it.
There's no buzz. No rush, no wired feeling, nothing that tricks you into overdoing it. Most days I forget I've taken it.
And here's the part that matters most if you have PEM:
When a better day comes, don't spend it all at once. Keep your limits where they are and let your baseline move first. I learned that the hard way.
One more thing, because I'd want to be told. CoQ10 is well tolerated by most people, but it can interact with blood thinners like warfarin, and with blood pressure and diabetes medication. If you take any prescription medicine, check with your doctor or pharmacist first. If anything doesn't feel right, stop.

The question everyone asks is "How long until I know?" Here's the answer — based on what Origin8 says and on what I and other customers with PEM have noticed.
-> WEEK 1–2: The Quiet Part
You will probably feel nothing. Your CoQ10 levels start rising in the first two weeks, but that isn't something you can feel. I didn't feel better. I also didn't feel worse — and with PEM, a new supplement that doesn't set you off is its own good news.
-> WEEK 3–4: The Small Signs
Many people start noticing a difference in the first 30 days. For me it was subtle… an afternoon that was slightly less wrecked. A phone call that didn't flatten me. Easy to miss, so write it down.
-> MONTH 2: The Laundry Test
Around week eight I did a small thing — folded the laundry — and waited for the bill. It didn't come. I didn't spend the next day in bed. To a healthy person that sounds like nothing. To me it was huge.
-> MONTH 3: Shorter Crashes
This is where most of us noticed it properly. The crashes still come. They're shorter. Instead of five days in bed, it's more like two. My baseline has lifted a little.
That's when I stopped saying "I'm trying a supplement" and started saying "this is the one I'm keeping."
Not cured. Functioning a little more like a person. And if day 90 comes and you feel no difference, you get your money back.
