I live in Florida- so I definitely deal with heat and humidity. Nuun has all the electrolytes you need- no reason to add in processed food of combos after. If you need food, do a protein drink and keep hydrating with fluids.

I put in 1-2 in bottle. If it is bad out I will put 2 in a big camelback bottle if my rides are going to be shorter(under 2 hours) I will put 1 in a small bottle and then the other bottle I use Heed or Skratch.

You may need to try different flavors, my fiance loves the cola flavor and the tea- I can't stand either. I like the orange a lot.

You may just need to learn that when you are pushing your body hard with physical activity you will feel different then when you are just walking around or sitting inside.
