Recovery drinks

Options
Does anyone have good options for a recovery drink/supplement. I am starting P90X/Turbofire. I have tried a whey protein shake, but for some reason it upsets my stomach after a workout. However, I can drink them for breakfast and be just fine. So I am looking for something I can have that won't keep me up all night either, as I have started doing workouts after the kids are in bed around 8p. I don't have enough time in the morning for a quality workout anymore.
