• It's been suggested to me that the best cure for my recent habit of waking up at 4 or 5 am and not being able to sleep again is to stay in bed until at least 6 am.

• Nonsense - or, as some of my friends would say, bullshit.

• I have discovered that a more effective cure is to get up immediately the dreadful feeling of awakeness dawns and blog about it.  If the post is truly crap you can always delete it later

• After a few nights you get so bored doing this you sleep on to a more reasonable time.
