For me to be so tired all the time?
Ok, so I'm 20 years old and I work alot at a scrap metal job. My problem is that no matter how much sleep I get, I always feel tired and sometimes fall asleep without meaning to. Now before this hasn't worried me, but it's bad since I finally got my license and I find myself almost dozing off at the wheel all the time. I always feel weak and tired and something i've also picked up on is a lot of a light headiness. At work if I lift something heavy, I feel like I'm dizzy and I've fallen down sometimes. In fact, I've fallen down in two instances when I was just simply walking and felt light headed all of a sudden.
Another thing is that the sides of my head sometimes ache or tingle.
Is this all normal?
