Other useful sleep aids..
If you experience interrupted sleep, remove the clock from your room, or cover the clock with a cloth.
Avoid doing mental arithmetic about anything - it keeps the brain thinking and stops you sleeping. Instead repeat in your head something positively reinforcing about going to sleep, like:
'Sleep-time is for sleeping. When I awake fully refreshed I'll be able to do all the arithmetic I want. But for now, sleep-time is for sleeping.'
If you are sleeping when or where there is light coming into the room, wear a sleep mask that keeps out all light.
This also helps keep you from opening your eyes at night and looking at the clock.
'Cal/Mag' (Calcium/Magnesium) tablets seem to help some people. The magnesium relaxes the muscles apparently.
Homeopathic remedies are worth a try too, for example Calms or Calms Forte by Highlands can be used by anyone, including children, without side-effects. Follow the instructions properly and seek appropriate advice for using any of this stuff if you are not sure.
It's very very important to cease the habit or the tendency to clock-watch, count the hours, remember the hours, and tell people the next day about lack of sleep.
Focusing on the clock, the time, and discussing sleep problems at length with others guarantees that insomnia or sleep disorders continue. So find something else to talk about instead.
Telling others that you cannot sleep is actually a powerful technique for reinforcing and developing insomnia - it's a self-fulfilling prophecy - so do something else instead - like following these guidelines.
When you know and accept that watching the clock and counting the hours and telling others about lack of sleep all cause insomnia it's easier to cease the habit. So cease it immediately.
Start telling people that you are now much better or sleeping well. That you are relaxing and feeling a lot more comfortable when you go to bed, and that discussing it in this way is all part of the cure.
Say it to yourself and to others, and follow these guidelines, and you will go some or all of the way to rediscovering, and then maintaining, your natural healthy sleep patterns.
Sleep well.
