Mariah Carey has had more #1 songs ever than anyone else except the Beatles. So she thinks that she is super-human just like you do. Several years ago she had a nervous breakdown. She said that it was due to lack of sleep.
If you need 12 hours sleep then you have another problem like depression or a brain tumor. See a good ND to see if he can figure it out. You could have mono. You could have Epstein-Barr. You could have tiny holes in your colon. You could have candida overgrowth. See this
webpage under headaches for advice on figuring out what is wrong. Also keep in mind that you pay someone and they try to help you for money like a prostitute. But nobody really cares about you except for you. "Physician heal thyself."
