I remember we had some note on us in Basic stating that we would drink between blank, but not to exceed blank canteens per hour.

I've heard of people dying from water toxicity, typically ecstasy users or people with serious OCD issues but they're usually drinking gallons of water. Here we're talking about a half gallon. I could easily chug this with no problem if I was hot and thirsty. Sure, I might have to piss a lot but it doesn't seem like a crazy amount.

Her electrolytes were probably already F’d up when she drank this is my guess.
I usually only put away half this after a hard workout, and half is aminos and half is Liquid IV.
I’m 6’2” and relatively muscular 215.

I do agree it seems unusual.
