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...
But in a pinch, ORT has been used worldwide. And very effectively!
Quite true. But now is the time to lay in a few packets of the Gatorade as it's currently pretty inexpensive and available. It's also ready to store long term as it is. That's a few bonus points in my mind.
After the SHTF you most likely won't be able to find any at all.
