It's impossible to suffer from insomnia.

Recently, I have a trouble to fall asleep, although I'm sleepy. Why?

When I'm too tired from terriblly busy work, I sometimes get into such a situation, but I'm neither busy nor tired now. Besides, as I often wrote on this blog, I primarily love sleep and in fact I really can sleep even all day.

It's after 3 o'clock at the midnight now...
