I'm wide awake

It is time to sleep and snore for others but not for myself. Yes, it's 11 PM already and my eyes are wide awake. I have no idea why I'm wide awake but I feel tired and my body needs to take some rest. I've been tired for two nights in a row from lack of sleep due to my left shoulder and neck is in pain. In the morning when I woke up the pain was a little better and I could turn my neck without saying ouch. Unlike the last 2 nights it was really worse, I could hardly move my left shoulder and neck especially when I laid down in the bed. Hopefully these 3 nights in a row with lack of sleep won't make me more sick and these wide awake eyes will close now, lol.
