How about something with carbohydrates added to your water bottle with half'n'half sodium potassium? Half'n'Half is available very inexpensively in the supermarket. Add a bit of sugar and flavouring and you've got yourself a very inexpensive beverage that you can tailor exactly to your needs/tlerances.
