What do you guys add to your water? I'm looking for a good powder mix, why it's good etc. I was looking at the gatorade mix packets, but am not sure if there's a better one for cycling or not. I've used hammer's heed mix, but I don't know if I should be focusing on getting energy or electrolytes or both.

Also should I take whey protein after a long workout? I usually eat some meat/peanut butter/milk, but I know all protein is not equal. Should I be getting a higher quality protein?
