Sleepy

I am always sleepy because of parties.
Here, I mean the problem is the "time lag".

Whenever I join a party, I stay up untill very late (sometimes till morning) so that my lifstyle is getting "nocturnal".
BUT!!!
This will be a really big ploblem, when I do not have any party.
I hope I could go back Japan now. ('cauz I have no defference in time now,hahaha)
Anyways, I haev to change my life style for the test...and travel to enyoy my trip 120%.

This is annoying.
For instance, I went to bed at 2 am but I cannot sleep untill 7am.
I felt so boring. So I did practivce of accounting text to get sleepy. (As usual, if somebody start to study something, he/she suddenly gets sleepy. Do you agree with this?) But I could not.
NOoooo!
So I woke up 11 am today and then did not take a nap.
This is typical stupid way, but I just want to sleep at the right time.


Santa Claus, please gimme good sleep in the night?
