TIFU by almost offing myself by drinking too much water (trying to prove to my wife it's not hard to drink that much)

My wife and I are getting back in shape. After our work out today I had a protein shake, large ice coffee, and some water.

My wife recently bought a 64 oz big refillable water jug and remarked how it would be difficult to drink the whole thing in a day.

I've always been good at chugging, could do a 5 beer trick in college, where I could chug 5 beers in a minute. So i thought 64 oz of water should be easy.

Filled the whole thing up and said, "Honey if I can drink this in one swoop you can drink it in a day."

I started chugging, she told me to stop, didn't listen and finished the whole thing in less than a minute.

5 mins later started feeling very not right. Was very nauseous and on the verge of passing out.

Felt like my brain was swelling and kept feeling like i could drop at any second. Researched over hydration and saw it can be deadly.

Luckily my wife is a nurse and started giving me salt. Still felt like something was really wrong and I would have agreed to call 911 at this point as my brain didn't feel right.

Was walking around trying not to pass out, and eventually sat down but would jump up when i felt myself blacking out.

Eventually started peeing a lot and after a few hours started feeling better, but it was terrifying. Don't drink too much water kids.

TLDR: Don't over hydrate it can kill you. If you do, eat some salt & pee.
