read the New Scientist in bed.

but staying asleep - maybe I have a clear conscience - only joking.

Apart from the trips to the loo, I sleep well enough unless I have problems at work or threats to continued work. Or women problems.

Thinking nice thoughts does work but it is not just a case of saying it - it has to be worked at. Try mental conundrums, arithmatic, learning song lyrics, what you would do with all that lottery money should you ever be so ........

basically crowd-out the thoughts that keep you awake and replace them with ones that will send you to ZZZZzzzzzzzzzzzzzzzzzzzzzzz
