Help - I Can’t Sleep

An article in The Independent details the following method, apparently used by the army, for getting to sleep quickly. Has anybody tried it? What do you think? It doesn’t mention how you make sure you stay asleep though …

Detailed in the book Relax and Win: Championship Performance, 1981, the technique is thought to have been developed by army chiefs to ensure soldiers didn’t make life-threatening mistakes due to exhaustion.

Here’s how to do it:
Relax the muscles in your face, including tongue, jaw and the muscles around the eyes
Drop your shoulders as far down as they’ll go, followed by your upper and lower arm, one side at a time
Breathe out, relaxing your chest followed by your legs, starting from the thighs and working down
You should then spend 10 seconds trying to clear your mind before thinking about one of the three following images:
You’re lying in a canoe on a calm lake with nothing but a clear blue sky above you
You’re lying in a black velvet hammock in a pitch-black room
You say “don’t think, don’t think, don’t think” to yourself over and over for about 10 seconds.

The technique is said to work for 96 per cent of people after six weeks of practice.
