So, i am sure all of you have heard of Morning wood, so there is no need for me to explain what it is. So, with that being said, i am also guessin that most can figure out what Night wood might be. I have never heard that term, Night Wood, but i am using it. It seems every nite i go to bed, i seem to get it. For no reason, and out of no where. Has anyone heard of this before?
