What happens to my muscles if I don't take some form of protein RIGHT before I sleep? 
I have a question about nutrition. What happens to my muscles if I don't take some form of protein RIGHT before I sleep?
Well, your muscles will still repair and rebuild themselves during sleep, but they may not have enough protein to do so optimally. This can lead to slower progress in building muscle and potentially even muscle loss over time.
