Eat and Sleep

Finally I feel hungry.
For don't know how long I always feel that my stomach is very full, don't have the appetite to eat.
But now, I can eat d~^^
Surprise of the amount that I put inside my stomach for lunch and dinner just now.

Finally I feel sleepy.
For don't know how long I cant sleep, body feel tired, but mind is awake.
But now, I can sleep d~^^
But I think is over d, like keep want to sleep, always feel sleepy....==''
