Anyone have a recovery drink they like (for endurance sports)

So to report back, I've started drinking whole milk and Nestle Quick (hey, it's cheap and easy to find) and it seems to work as well as "chalky white" (aka Hammer Recoverrite) at about 1/4th the cost per glass. I still take Chalky on the road with me since water is easier to procure than milk in a hotel in another country at 7AM when trying to get ready to go to work, but so far the Quick rabbit and I are getting along well. It is also much tastier than Chalky.
