It's not water. Not true. It's whatever liquid you have around you. I had 8 scotch and cokes, and I don't even drink. Kept putting my hand up. So thirsty. I've had 2L of orange juice when it was meant to be brought home. Same with milk. The best way to quench it is bobba iced teas x2, and sweet drinks like coke. Anything else may keep you thirsty.
