I have learnt 2 useful techniques about getting off to sleep that I am happy to pass on.Well, I'm having a rough time sleeping, so I'm re-organizing my scrapbook stuff and herding cats.
Firstly, resist fidgeting/moving around a lot in bed. This sends a message to your brain that you are not relaxed. It requires a bit of effort to keep still when you want to move but it really works in terms of preparing the road to sleep! Also, note your facial expression. Very often we can have a tensed face. Consciously relax facial muscles. This too will send the right message to the brain, re. relaxation.
