“Coke is NOT a thirst quencher! Neither is beer! BOTH caffeine and alcohol (which I “believe in”)are diuretics- they dehydrate you by drawing water out of your system. “
That’s incorrect. Since they have caffeine, alcohol, sugar, etc, they are not as good at hydrating you as water would be. But if you were stranded on a ship with only Coke, tea, or beer you wouldn’t die of thirst.
