CHAPTER SEVEN

What It Actually Does to You

ALCOHOL IS ONE of the most widely consumed psychoactive substances on the planet and one of the most misunderstood.

We know how it feels.
We know what it does to our night.
But most people have no clue what it’s doing to their brain.

Spoiler:
It’s not “loosening you up.”
It’s reprogramming your operating system in real time.

Alcohol is absorbed primarily through the small intestine and it doesn’t take long to hit.

Depending on your weight, metabolism, food intake, and liver efficiency, you might feel it in 10 to 20 minutes. But once it’s in your bloodstream, it’s everywhere.

The brain. The liver. The kidneys. The skin. Emotions. Decisions.

It slows down the entire central nervous system like someone’s dragging their finger across a record player.

But it doesn’t shut it down right away.
That’s the trick.
It remixes everything just enough to make you feel… better.

At first.

Here’s what alcohol starts messing with the moment it crosses the blood-brain barrier:

GABA: The “chill out” neurotransmitter. Alcohol boosts GABA, which relaxes your muscles, lowers anxiety, and makes you feel warm, loose, and social. This is the part you like.

Glutamate: The “wake up and think” neurotransmitter. Alcohol suppresses this, which slows down reaction time, memory formation, and complex thinking. This is why you start forgetting stuff, including whether sending a “u up?” text is a good idea. (It’s not.)

Dopamine: The pleasure chemical. Alcohol spikes dopamine in the reward center of the brain temporarily. You feel confident, bold, maybe even euphoric. But the dopamine surge is borrowed from tomorrow’s mood.

Serotonin: Your long-term mood stabilizer. Alcohol gives it a little boost too, but it doesn’t last. And when it drops? Welcome to the hangxiety.

One drink and you feel brave.
Two drinks and you’re hilarious.
Three drinks and you’re invincible.
Four drinks and you’re telling someone you’re gonna start a business together.

This isn’t magic.
It’s your prefrontal cortex, the part of the brain that handles judgment, risk assessment, and impulse control, getting dialed down.

That voice that says, “Maybe don’t do that”?
Yeah, he’s been roofied.

You didn’t get more fun.
You just got less aware of what wasn’t fun.

Alcohol messes with the hippocampus, the brain’s memory vault.

You can be walking, talking, laughing, and not forming a single long-term memory.
That’s a blackout, and it’s scarier than it sounds.

You’re not passed out.
You’re just not recording.

People often describe it like “time skipping,” or watching a movie that keeps cutting to the next scene without warning.

You’ll wake up and wonder:
Did I really say that?
Did I actually go there?
Was that me?

Yes. It was you.
Just the version of you with the recorder turned off.

Alcohol turns down your anxiety, pumps up your craving for comfort, boosts dopamine just long enough to trick you into seeking emotional resolution, and disables the voice that says,
“Let’s sleep on it.”

So when your brain goes looking for something familiar, emotionally charged, and unresolved?
Bam. Ex.

Your thumbs move faster than your conscience.

Then the morning hits.
And you wonder why your Messages app is a battlefield.

Alcohol doesn’t give you new skills.
It just lowers your filter.

If you’re already a good dancer, it might help you loosen up and hit the floor.
If you’re a bad dancer, you’ll just think you’re great. (You’re not.)

Same with aggression.

If you’re already holding anger, resentment, or sadness, alcohol will let it spill.
Sometimes literally.

People don’t become different when they’re drunk.
They become less censored versions of who they already are.

That first drink really does have magic.
Not because alcohol is good for you, but because your brain is wired to reward relief.

That sigh. That shift. That buzz.
It feels like home because it’s the absence of anxiety.

But you never drink just one.

And the brain doesn’t like being tricked.
So it adapts.
Tolerates.
Punishes.

That’s why the first drink gives you wings and the fourth one gives you vertigo.
