i disagree ith eating protein right after the big workout.
your body needs electrolytes and glucose (sugar carbs etc. ) stuff like oranges, juice or whatever to replentish is forst order of bisiness. Your body is not ready to start reparing that muscle for at least an hour. You need to eat something that is going to give you a bit of an insulin spike to spike the glucose into the muscles. Muscle repair comes later thus the need for protien intake later.
