Sleepy Days

It's just SO WEIRD. For the past few days I've been feeling sleepy a lot during the day for no reason! I mean, technically speaking, I am getting enough sleep (we didn't really have any homework for the past few days so I went to sleep at 10:30pm and woke up at 7:30 everyday since Monday). There. I don't know why I am feeling sleepy. I am eating right, exercising right, and sleeping right, BUT I STILL FEEL KINDA SLEEPY SOMETIMES! Nuuuuuuuuuuuuuuuz. I am scared. This has never happened to me before. This.is.seriously.freaky. And the weird thing is, if I manage to go beyond my sleepy time, I would get super hyper that it would take a long time for me to calm down. Another freaky thing. o.o
