Sugar dehydrates you.
There is not enough water in a bottle of soda for your body to process the sugar in the soda. This is why soda dehyrates you.
Gatorade has sugar. Which undoes all the other ingredients.
I know a national certified athletic trainer that says for 1 bottle of gaterade you need to drink 8 bottles of water.
I'd skip the gaterade, eat a banana, and have a salted pretzel or salted bagel, and keep drinking water so my urine stays clear.
