oooh, just stumbled on this post.. hope you don't mind... I have the same trouble at times TK, my mind just goes over and over things that have happened - even from years ago... I just can't get to sleep. Hence me being here now.
I do puzzle books before I try to sleep. That does work for 90% of the time. I read once that you have to do something boring, or mindnumbing to get back to sleep... I think it was something like dusting,cleaning the basin or whatever.
Do you have tea or coffee in the evening? Sometimes drinking any liquids can keep the brain going on and on. I love a cuppa before I go to bed - that, I know is my problem but I try to have decaff tea (yuk)... not the same but a good compromise. Smoking too can often be a cause, alcohol, food too... its not good to go to bed hungry but also as bad to eat close to bedtime.
On the other side of the coin, exercise - plenty of it but not too close to beddybise. yes, any sort...
Also, having a nice hot bath or shower is NOT good for you before bed. The heat from the water rushes the blood round the body, opens up your sinuses, pumps all that energy into the brain etc... a hot bath or shower in the morning is best for the day.
A cool shower, dip etc is best for relaxing and ready for bed.
Have you tried herbal tabs such as Nytol? DH uses them occassoionally. He is snoring like a gorilla at the moment. Hope this helps... try to do some relaxation exercises too... that will wind you down from the day and calm the mind... allegedly.
