Gatorade (only slightly OT)

You dont need potassium- sweat losses are all sodium, Oral rehydration
solutions are for treating severe vomiting and diarrhea, and even then
it is little ones more at risk. Adults have large reserves. You don't
have to put the salt in the drink either. Foods can contain plenty of
sodium, and usually do.

Drink what tastes refreshing to you. I find plenty of ice is most
important.
