Hello! Drinking milk before going to bed, due to the fact that milk contains a lot of calcium, after drinking it and then going to bed, calcium can not be excreted on time, it is easy to be deposited, so it may cause kidney stones. Drinking milk before going to bed is possible to cause kidney stones, but not absolute, this also varies from person to person. Pay attention to yourself. I'm not sure if you're going to be able to do that!
