I would get some blood work done, Kajero. You should not be that tired. I am only 2 years younger than you, I get up at 4:45 2X a week to go to boot camp, and then I go to work for 5-9 hours. I do need to sleep later (but not by much, always up by 6:15 or so) on the other days. You can't be your best if you aren't sleeping. No wonder you are tired. There's lots of reasons for sleep problems; get a check up and if everything comes back all clear, do some reading on sleep hygiene. A lot of sleep disturbance comes from not being able to slow our brains down; my prescription to my clients is meditation on a regular basis.
