Always sleepy at school, but nowhere else...?

Question

I get about 8 hours of sleep before I go to school every day, but for a while, it has been extremely hard to stay awake in class. I can come home and be fine, and I'm fine when I'm driving to school, but as soon as I get in class I get extremely sleepy... I've had a full physical, and blood test, and they came back normal. I eat breakfast in the mornings, and take One a Day multi-vitamin. I'm 17, and I'm a junior in High School, going to bed around 10:00 p.m. and waking up about 5:45 a.m. and neither myself or my parents have any idea what's wrong, or what to do.

Answer 1

Its because school is boring and you have to sit and not move pretty much all day

Answer 2

Are you bored at school?

Answer 3

dont skip breakfast - its the most important meal of the day

Answer 4

you hate school. you think its boring. i'm like that and im homeschooled.  

Answer 5

I think it's the 5:45 a.m. that's doing it. 7 1/2 hours asleep isn't really that great, + that's not natural for any human being to wake up that early.
