Just to add to this nutrition-near-your-workout thing:

I usually take in some carbs along with my protein postworkout. Usually it's a half-cup of oats and a Nutri-Grain bar/granola bar. That way I get some good complex carbs (oats) and also something a little more simple (the bar).

So it breaks down to:

46g protein from powder
27g carbs from oats (also adds another 5g protein)
~25g carbs from granola bar

Anyhow, I've definitely seem some good results in the past couple months since I started really monitoring my diet and protein intake. I try to hit my bodyweight in grams of protein per day and I make sure to drink enough water so my body can handle that extra protein.
