Thoughts in the small hours

Just a thought, the longest hour in the day is bettween 04:00 and 05:00. Your bladder wakes you up, relieve yourself, then you can't get back to sleep. You lie there thinking all sorts of thoughts, some gloomy and some not? sometimes i say i shall put these thoughts on paper, i read them later and wonder what i was going on about and other times i think that was quite lucid and illuminating. But majority of times it is just dribble.
