for years I had the problem of going to bed around 10pm and then lying there awake for hours
Do you do any sports? Running or swimming for an hour (or cycling for two) works well for me.

Edit: see above - I realised that sport actually kept me awake (tossing and turning, not falling asleep within 20 minutes).
That looks like FUD from somebody who's living depends on blogging FUD. Of course, it's possible to train too hard, but this is very bad advice for the average (slightly overweight, not very active) person. If you worry about training too much, go talk to a sports physician and take a cardiac stress test. Or just run so slowly that you can breathe through your nose only.
