I usually make a pre/during workout drink that consists of about half a scoop of Fruit Punch flavored whey (Optimum Nutrition brand), and powered Gatorade (fruit punch flavored also). I like Optimum Nutrition, since it has BCAA's and various other nutrients in it - though I'm sure most high quality brands have the same/similar stuff.

After workout, I put a scoop of "Glyco-Maize", by Optimum Nutrition (an unflavored carbohydrate powder), milk, a frozen banana, frozen strawberries, and about a scoop of chocolate whey and blend it up for a delicious smoothy. That REALLY hits the spot after a workout.

Loaded up with carbs/protein and energy, I can take a long shower and go about preparing a big fat meal, without worrying about trying to hurry-up and get nutrients into my starving muscles.
