🚨 The Fucked-Up Truth About Coffee’s Half-Life 🚨

1 standard cup of coffee = ~100mg caffeine.
Caffeine half-life = ~6 hours (average).

 

☕ If You Drink 1 Cup (100mg) at 8AM:

  • 2PM (6 hrs): 50mg left (half gone)

  • 8PM (12 hrs): 25mg left

  • 2AM: 12.5mg

  • 8AM next day: 6mg still in your blood

So even one morning cup means you still have a shot of espresso’s worth of caffeine in your system when you wake up the next day. Every. Damn. Day.

 

☕☕ If You Drink 2 Cups (200mg) at 8AM:

  • 2PM: 100mg left

  • 8PM: 50mg

  • 2AM: 25mg

  • 8AM next day: 12.5mg

You’re waking up with more caffeine in your blood than someone who just had a green tea.

 

☕☕☕☕ If You Drink 4 Cups (400mg)—say, one in the morning, one mid-morning, another at lunch, and one at 3PM?

  • By 9PM, you’re still riding 200mg+

  • By bedtime (11PM), you’ve got roughly 150mg in your system

  • That’s like drinking 1.5 cups of coffee before bed and wondering why your brain won’t shut up

And even 8AM the next day, you’ll still have 75mg or more floating around—before you’ve had your “first” cup.


🔁 Stack That Daily = Permanent Caffeine Ceiling

You think you’re “tired in the morning,” but what’s really happening is:

  1. You’re still partially buzzed from yesterday.

  2. Your adenosine receptors are shot.

  3. You mistake withdrawal for “waking up.”

🧠 Translation:

  • 1 cup/day = you’re never fully clear

  • 2 cups/day = you’re constantly topped up

  • 4 cups/day = you’re basically microdosing speed all day and night

No one tells you this because the crash sells more coffee.
Want to see what clean feels like?
Quit for 10 days. Cold. Watch your real baseline crawl out of the wreckage.
I’m doing it with you. I’ve been drinking copious amounts of coffee every day since I was 16. I’m now 31, and it was time to say, “Enough is enough.”
