None of those post were helpful, so stop being a douche.  Your post was just as stupid, it's not like he's having some trouble sleeping tonight because he had a Red Bull.  He hasn't slept in 4 days!  You can't just read a book and be good to go, my mom has insomnia and she uses a suscribed pill just to fall asleep every night.  I would recommend you go see a doctor bro, the longer you wait, the worse you will feel.
