I think both you and the parent post are correct. I heard similar advice playing soccer: when you drink water during a game, what you usually do is drink it fast (and in a hand wavy way where the bottle is in the air). So the speed allows for more water and air, and thus you feel cramps. If you were to drink it slowly, which will reduce the air most likely, then you have less risk, but as a kid playing soccer, the urge to go back to the field is is too great. :)

Absolutely. This is worse when eating soup. You'd have to be veeeery careful when eating soup with a spoon. I always hated eating soups as a kid coz I'd feel so bloated after.
