Drink plain water and eat some burgers. Food and electrolytes in one step.
I'm too cheap to buy cooked burgers when I can buy 1-2 lbs ground meat and some buns for the same price, cook it and have 4 burgers vice 1.
Then again, I was asking whether people carried electrolyte mix or not - not how to get around carrying the mix.
