Could Taste a Little Better
I think this mix did give me a little extra energy the other day when I had two tennis practices nearly back to back.  I have tried this mix several times and though I haven't noticed a jolt in energy, I didn't get overly fatigued either, especially while playing in the hot sun.  It mixes well with plain water though it seems to settle out a little bit if left to sit in the glass for a while.  The flavor is not all that good - it has a strong, almost bitter flavor that I don't really care for.  I have since started mixing this with another electrolyte mix that has a sweeter and more pleasant flavor.  I like the combination and it really keeps my electrolyte level up when sweating and exercising in the heat.
