Last night I didn't go to bed till 6 am!
There's no particular reason, certainly no stress, health problem or outside disturbance. I just get into this rut of another chapter of a book, another sudoku (
) another cup of tea, another post on YACF, etc. Then it gets cold and I need another cup of tea or to put the heating on cos I hate going to bed cold. I sometimes put it down to a latent self-destructive tendency which expresses itself in this way because I don't smoke and hardly drink - though I do not think beer is the answer.
