after your suggestions and more research i purchased gookinaid - hydralyte.
Thanks for the follow-up report. I'm glad that Gookinaid seems to work for you.
You didn't mention getting any other flavor, but for what it's worth, I would consider orange to be the "strongest" flavor. And I say strongest in the relative sense, since compared to other brands, all of the Gookinaid flavors are quite mild.
