First of all, I am almost never tired. It's not just that I can't sleep, it's that I don't feel the need to. Other times, if I am tired, I just cannot sleep. I don't know why. I don't drink anything with caffiene in it, smoke, do drugs or anything like that, that would keep me up. I have been going to bed at 5 in the morning for the last week or two. Then, since I have nothing better to do, I lay in bed ( not sleeping) until about 3 or 4 in the afternoon sometimes. It can be random and it isn't good. I try to get to bed early, but I often have a ton of homework that needs to be done, as well. I love sleep, I just don't get tired or simply can't! I suppose it's pretty normal for a lot of people though. So I guess it isn't that "different" but it's wierd as in not normal and healthy.
