Sleeping more

In general, I am a night person.
I like to read, write and think late at night.
Since I was a little girl I thought that
falling asleep was cutting me out of
what I liked doing.

After arriving in the States, I am sleeping
more hours.
True, I am not able to sleep more than two
or three hours in a stretch, but I usually
sleep a few cycles like that.

Here I find that I am extremely tired
in the early evening.
Two nights ago I went to sleep at eight o'clock
in the evening and got up the next morning
at six thirty!
Last night I fell asleep at nine, and got up
at seven.
Weird!
