Literally just did an exam on this in uni today so i will try my best here...

1. alcohol affects a part of the brain responsible for fine motor skills, hence why we get 'sloppy' when we drink i.e slurred speech, staggered walking etc.

2. adrenaline (and noradrenaline/epinephrine/norepinephrine) is a neurotransmitter (NT) released by something in your body called the 'sympathetic nervous system' (SNS).

The SNS is your fight/flight response. If you see something that requires tou to activate this system, such as a fight or you see someone in need of medical care while you're drunk, adrenaline is released.

Adrenaline is a very short lived neurotransmitter. It doesn't hang around for long (typically), enough to get you to safety either by punching your way there or running.

Adrenaline is a super powerful NT and overrides the relaxed/sloppy state you're in by allowing you to be hyper alert of your surroundings and energised.

Once your body no longer needs the use of the SNS, you will usually experience an 'adrenaline dump' in which you may cry, feel very exhausted and weak or feel like your sloppy old drunk self again.

TLDR Adrenaline et al doesn't sober you up, it just makes you hyper alert thanks to fight/flight.

P.s somewhat unrelated, incase you've ever wondered about 'breaking the seal' while drinking... Alcohol ibhibits the production of a hormone called ADH (Anti diuretic hormone). ADH is used in the body to retain water so you don't dehydrate. Alcohol stops this hormone being produced so you pee... A lot... And its very clear. Its not clear cos you're 'hydrated' its clear cos your body is dumping all the water out of you as nothing is telling it to retain it. #funfact.
