I had Powerade and Emergen-C earlier. Now I've moved on to more water, as usual.
I'm not a fan of the powerade, except in the middle of the summer, during a long ride. And even then, I have to water it down to be able to stomach it.
The Emergen-C... I love that stuff. My housekeeper told me about it a month ago, when I was trying to avoid the cold going around. That's how I'm taking my vitamin C a lot of days, now. Pour it in a glass of water when I come in from a run, and I get to rehydrate & take vitamins all at once. (I like multi-tasking, if you didn't know.)
