I found ElectroMix at the Water & Ice located on Lindsay, just North of University (West side, North end of strip mall). I have not looked at Hi-Health, I think they carry Emer'gen-C. You can also order from the site, But I too would like to try before I buy.
In ref to CindyC
, That taste i.e.: yuck I find only during extreme exertion, pushing your body to your limits, where your stomach can't absorb the excess sugars you just drank (sweet sports drink), this can lead to a heaving encounter. I don't know of anyone doing this who is not in a race situation, no need to push your self this hard on a hike
With heat stroke, it is important to get water and return your lost electrolytes, too much sugar is not good and will inhibit rehydration.
