The Yeti drink mixes are great to mix in with 1 scoop of NOS Yeti blue raspberry, black cherry or raspberry and then tablespoon of honey, several squirts of lemon juice, and 1 bag of red zinger hibiscus herbal tea. It doesn't suck and you can drink almost a whole 64 oz of liquid during a workout. It isn't too sweet but takes care of quenching thirst. I think hydration really is a key when you are working out hard to maximize thermogenic and aerobic results.
