Does it happen to You too?

Sometimes when you are going to sleep and you decide to watch a few funny youtube vids like those of Key and Peele and then the "few" videos you wanted to watch turns out to be too many because those funny vids made you so engaged that you lost your sleep.

I don't mean it necessarily has to be funny vids only. It could be any distraction. Say you decide to read about Queen Nefertiti of Egypt on Wikipedia and then from one wiki page to others you go on reading for hours. I know it happens to me many times when I am reading about the dynasties of any ancient civilization.

Or are you a very strict person and if you decide to watch a few vids or read a few pages then you stick to your commitment?
