Or you could buy those little Gatorade packets and mix them into twice the recommended amount of water.
The gatorade packs might even be better, because they have potassium in them. You don’t want to run out of potassium, that could cause cardiac arrest...

That’s a great idea. Being hermetically sealed, they would keep for quite a while.
I haven’t seen them around. Where in the grocery store do you find them?
