After I go out for a long ride, I have been told that it's a good idea to take in a lot of protein to help with muscular reconstruction while sleeping. To assist in doing this, I have started drinking milk mixed with protein powder (20g whey protein) after my workouts, usually an hour or two before I go to bed.
Does the time that I actually eat or drink protein matter? Would it be less effective to drink it right before going to bed or too many hours before then? Is there a recommended ratio to go by?
