We Googled Gatorade after realizing how much the cost of this product adds up. This is the result of much trial and error. The envelopes with non Kool-Aid drink mixes (like Wylers) are usually more like Gatorade. Kool-Aid seems to have its own distinct flavor. I often double the recipe to make a gallon jug. Fructose and citric acid might require going to a good health food store or brewing supply co. but yield a product more like the original. It is very good with the substitutions mentioned if you like the lemon flavor.
