Hey Fire,
My mum taught me it years ago, she is a nurse.
The way I do it is:
Get a glass, fill half of it with Coke.
Put in 1 spoon of sugar (this flattens the Coke and adds more energy)
Add a pinch of salt, for the electrolytes.
Fill the rest of the cup with water.
It's kind of like those rehydration drinks but it tastes a lot better.
