The Real Price of a Caffeine Habit
Few people ask how much of their morning brain health is actually working for them and how much is borrowed from later in the day. I didn't, for the better part of thirty years spent running other people's numbers instead of my own. A dependency doesn't show up on any balance sheet until you go looking for it, and once I started cognitive tracking my mornings and testing a caffeine alternative side by side against the espresso, the coffee line item turned out to be carrying more debt than I wanted to admit.
Before the comparison gets going, the standard disclosure: I balanced books for a living, not brains. I'm not a doctor, not a neuroscientist, and nothing here should replace an actual conversation with your own physician, especially if memory or focus problems are new for you. What follows is one retired accountant's spreadsheet, not a clinical study.
My own caffeine habit ran deep — a shop-bought espresso or two before 7 a.m., another by mid-morning once the first one wore off, and a nagging sense that the whole system was propped up rather than solid. Coffee doesn't fail all at once. It fails on a curve. Caffeine has a half-life — nowhere near instant, but nowhere near all-day either — and somewhere around late morning, a good chunk of that first jolt has already checked out, taking my sharpest hour with it.
Add up the daily habit over a month and you get a three-digit number that would have made me raise an eyebrow at a client — and did, once I finally ran my own routine through the same spreadsheet I used to run theirs.
Can a Caffeine Alternative Actually Replace a Double Shot?
Somewhere in that audit, I swapped the extra espresso shot for something built around what its makers call auditory brainstem response — an audio-based approach called The Brain Song. I won't pretend to understand the neuroscience behind that term; that's a different professional's spreadsheet, not mine. What I can audit is whether my own numbers moved, and by how much.
Neil Trevisan, who sat two cubicles from mine for eleven years before we both went semi-retired, is the first person I call whenever I want somebody to poke holes in my logic. He'd already sent me a debunking article about audio-frequency supplements — at something like eleven at night, which is when he always sends those — before I'd even placed the order.
Six Months of Fish Oil Did Nothing
Before any of this, there was a six-month stretch of fish oil capsules from Costco, taken every single morning, following the serving size on the bottle to the letter. Nothing moved. Not the focus numbers, not the recall numbers, not even the subjective sense of things feeling less foggy by mid-morning. In accounting terms, that's still a result — a flat line is data too, even when it isn't the data you wanted.
What a label promises and what actually shows up in my weekly numbers are two different columns on two different pages. They don't always reconcile, and the fish oil months are the clearest example I've got.
None of this is a controlled trial, and I'm not going to dress it up as one — separating a genuine signal from a placebo bump is its own audit, kept in a different tab entirely, not this one.
Reading My Own Numbers
The clearest memory I have of the shift wasn't a big one. Sitting on a bench at Klyde Warren Park downtown on a Sunday, I finished the crossword in well under fifteen minutes without once reaching for my phone to check a clue — the kind of small thing you'd never log as a data point until you're the sort of person who logs everything.
My first 30 days of testing already showed a gap between the two approaches on my own scorecard, and it held up through my 90-day memory results too — focus scores that used to sit in the high 60s were holding closer to the mid-80s. Verbal recall moves on its own slower timeline, separate from focus, and I track it in a different tab entirely. Whether the return justifies the ongoing cost of any one supplement is its own ledger, kept elsewhere. Afternoon fog, for what it's worth, is a different problem with different causes — this comparison is strictly a morning one.
A reader named Dorinda Szymanski, a retired nurse up in Wisconsin who found my site through a Reddit thread and started keeping her own numbers not long after, mentioned in the comments once that her scores had climbed in almost the same shape as mine, give or take a few points. Seeing someone else's spreadsheet rhyme with your own is a strange kind of confirmation — not proof, but not nothing either.
The Genius Song and NeuroPrime Comparison
Two other names come up often enough in this space that they deserve a mention rather than a full supplement review of their own. The Genius Song follows the same audio-based logic as the one I tested, and I've started running it through afternoon sessions, though I don't have enough weeks behind it yet to trust the numbers the way I trust my morning data. NeuroPrime takes the more traditional capsule route, which will appeal to anyone who never liked the idea of headphones as a health tool in the first place — a reasonable instinct, even if my own data currently favors the frequency-based side of the comparison.
Why the Tracking Method Matters More Than the Supplement
None of this works without a consistent way of measuring it, which is the part most people skip. I've written up the actual structure — the guide to brain health spreadsheets — for anyone who wants to replicate the method rather than just take my word for the results.
So Which One Wins the Audit?
My wife pointed out, almost as an aside, that she hadn't been asked where the reading glasses were in longer than she could remember — which is the kind of evidence that doesn't show up in any spreadsheet column but probably belongs in one.
So here's the actual audit result, side by side. Caffeine wins on speed — nothing beats an espresso for a fast, cheap jolt when you need to be sharp in the next ten minutes, and there's no shame in reaching for it before a big meeting. A caffeine alternative like The Brain Song wins on the slower, steadier column — fewer swings, less of a crash by mid-morning, and numbers that held up over months rather than hours. If your mornings are a sprint, keep the coffee. If they're a marathon and the mid-morning crash is the real problem you're trying to solve, the frequency-based approach is the one my own spreadsheet ended up favoring.
