Confessions of a Coffee-Dependent Developer: 4 Cups Minimum

The 9:17 AM Ritual

The first thing I do when I get to work is not opening my code editor. It's brewing coffee.

Standing in front of the break room drip machine, placing my mug, pressing the button — that's when my day begins. Without this ritual, I can't start working. Not that I'm physically incapable — it's more like I'm psychologically not ready.

First cup: black. No milk, no sugar. The bitterness feels like it wakes up my brain.

But here's the thing — caffeine reportedly takes 20-30 minutes to actually kick in. So what's the clarity I feel the moment I drink it? Placebo. Definitely placebo. But if placebo works, isn't that still working?

The Four-Cup Timeline

Cup 1: 9:20 AM. Right after arriving. Survival mode. Cup 2: 11:30 AM. Before wrapping up morning work. Focus boost. Cup 3: 2:15 PM. Post-lunch drowsiness. This one's mandatory. Cup 4: 4:40 PM. The final push before leaving. Though drinking at this hour sometimes means I can't sleep at night.

Sometimes there's a fifth cup. During overtime. But after five, it's not alertness — it's trembling hands. Heart rate goes up too. That's when I think "okay, this isn't good" and switch to water.

(Then the next day I drink four cups again.)

I Tried Quitting

Last November, I attempted a caffeine detox. A three-day no-coffee challenge.

Day 1: Headache. From morning, a throbbing pain. They call it caffeine withdrawal headache. So that's a real thing. I took ibuprofen.

Day 2: Headache subsided, but the drowsiness was unreal. At 2 PM I closed my eyes in the bathroom for five minutes. Didn't go in to sleep, but didn't set an alarm either.

Day 3: I gave up. Specifically, a coworker said "are you okay today?" and I had a coffee. That first sip. Like finding an oasis in the desert.

Couldn't even last three days. A willpower issue or a physical issue — hard to say.

What Percentage of My Salary Goes to Coffee

I did the math. Company coffee is free, so excluding that — just what I buy outside.

Out of five workdays, I buy from a cafe about twice. Americano, 4,800 won. Sometimes a latte, 5,500 won. I also hit a cafe once on weekends. Monthly total: about 52,400 won.

Maybe that's a lot, maybe it's not, but annualized it's 628,800 won. Six hundred thirty thousand won on coffee. I'm not going to play the "imagine if I invested that" game. I'm not quitting anyway.

A Coffee-Free Future

What if coffee disappeared from the world? I had this completely pointless thought during lunch.

Global developer productivity would probably drop by 37%. That's pulled from thin air, but I don't think it's far off. There's a joke about Silicon Valley grinding to a halt without coffee, but it might not be a joke.

I have no plans to quit coffee anytime soon. I know it's a dependency, but I'm not convinced it's harmful. There are studies about antioxidants and whatever. Cherry-picking studies that support my habit is probably a symptom of dependency in itself.

Tomorrow I'll be at the break room at 9:17. Place the mug, press the button. That's my morning.
