I'm interested if anyone has any improved, cheap to make, hydration solutions, compared to Dr Bell's Gookinaid (mix of Salt and Potassium in water). Ideally I'd want something less reliant on lots of sugar. The classic WHO recommendation was 1 tspn salt, 6 tspn of sugar in 1 litre of water. From what I can vaguely parse from this document:- http://apps.who.int/medicinedocs/en/d/Js4950e/2.4.html#Js4950e.2.4 That might be somewhat less now. Thanks for any help.
