Unfortunately, unflavored Pedialyte does contain sugar (Dextrose is
sugar).

There is a homemade remedy that people have been using for years:

1 tsp salt
1 tsp baking soda
3 tablespoons of sugar
5 cups of distilled water

Stir well - it keeps for 3-4 days in the fridge.

I don't know of any that don't contain sugar.  Any ideas?
