ok, hamster one - or other small furry animal of your choice (sfaoyc).
Imagine that you have a sfaoyc on a wheel in your head. it is constantly running on the wheel, and the wheel has a slight but very irritating squeak. The noise is incessant and is keeping you awake.
Give your sfaoyc a name; see it in full colour - the more detail in which you see it, the more effective this trick is.
Now, take your sfaoyc out of the wheel, talk to it, be nice to it, give it a seed or nut and stroke it to sleeeeeeep. Tell it that it is ok for it to rest, that the wheel will still be there in the morning if it really wants to get back on it. Soothe your sfaoyc until you see it getting sleepy... then its eyes will close and it will go to sleep - and then you can too, because the noise of the wheel has stopped.
The more you concentrate on seeing this, the higher the likelihood of it working.
I must go now as my neck has just gone into conniptions from being on the computer too long but I will be here again tomorrow for you. I hope that the above helps you sleep and if you need it, that someone else comes along to chat to you.
((((((((hugs))))))))) for you (and j), love and light
