The parts of the brain effected by adrenaline are parts related to immediate survival.

It is like giving a surge to your drunk brain so that you can temporarily not die, but it doesn't rid you of your drunkeness at all, it just gives you a chance to fight off your attacker, or whatever is happening.

This is what I figured. I've been in situations where you immediately feel "sober". Would it be fair to say that that feeling is just your brain saying "We need to focus on this thing and only this thing right now"?

Its kind of like being hijacked.

Adrenaline is a hormone with incredible "go go go" power, so let's pretend your brain is a car.

When you are drunk, the driver (you) is just slowly cruising along, swaying around, minding their own business, but oh no! A truck is heading straight for you.

Suddenly you passenger, adrenaline, sees you don't know what the fuck you are doing, so they yell in your face to step on the gas, grab the wheel from you and swerv you out of the way to safety.

After the danger has passed and you both quit shitting your pants from fear, you both chill out again and you can resume swaying slowly down the road like the drunk monkey you are.

Make sense?

It does, and I love a good, clear metaphor.

Thank you.

Just to be clear, the adrenaline does NOT improve your balance, coordination, reflexes, or judgement.

It doesn't do that under normal circumstances either. It's not a "skilled action" hormone. It just takes all the safeties off your normal systems. Heart rate and respiration spike, oxygenated blood is shunted to skeletal muscle and away from non-survival-essential equipment (like your forebrain and digestive system).

You might lift a car off somebody, but you may not be able to get the safety off on a firearm or get a key into a lock. You could also pull so hard that you tear muscles and tendons in your own limbs. That increase in HR and respiration can result in passing out from hyperventilation.

It will still do all that while you're drunk, but the fine motor coordination issue will be even worse, sensory feedback will be even duller (increasing injury potential), and god help you if you need to make any decisions.
