Homemade Electrolyte Drink

Electrolyte Drink
1 quart water
1/2 tsp baking soda
1/2 tsp table salt
3-4 Tbsp sugar
1/4 tsp salt substitute (can be found in the grocery store near the salt)
Mix well. Can be flavored with lemon juice or sugar-free KoolAid.
If someone is having trouble keeping down any fluids, this can be spoon fed. Some will prefer it cold, others just room temperature.
