P90x alternative recovery drink?

Okay so all this time after I finish working out with P90X, you know how Tony horton says "Drink that recovery drink after this.. you're going to need it.." So every work out I always drink my whey protein powder right away maybe a minute or 3 delay. I put it in a cup with water shake it and drink it. Does this count as a recovery drink? I can't afford any high price products. I don't drink any whey protein on my recovery days.
