I had insomnia which lasted decades that ended a few years ago. these are the tricks that got rid of it. have just been diagnosed with FM and now find myself facing sleepnessness again. argh! here are the best things I found:
Sunlight. NO sunglasses, windows or barriers of ANY sort. direct. preferably when it is out from the clouds, not hiding behind. There is a certain sun wave length which cant go through clouds, plastic, glass etc etc, that changes our hormones and brain pattern. about 40 minutes a day is great. the start of the day is great. i used to try and get at least 2 x 20minute sessions a day. Also, i live in australia and permanently have gallons of suncream on me, but found if i created a little bit of skin without it (any place besides the face neck hands etc where i was concerned about ageing) helps too.
mental stimulation - compoletely rethink your concept of this, and avoid it!. I used to watch tv in the evenings to relax - turns out this causes a certain stimulation within your brain, which totally destroys sleep. I had to avoid crossword puzzles, book reading - the exact things I thought were 'relaxing' me! Life has its jokes thats for sure. I found the best way to 'change the brain waves' to a sleep inducing alpha state were to choose other activites that where intrinsically simple and happy. for me that was things like patting the pets, talking with a happy and chilled out friend (easy going happy stuff, not issues, problems, things to do etc etc), sex, doing the dishes, enjoying going outside and breathing the lovely night air/looking at the stars, rubbing my fingers through the dirt, (interacting with nature was definately a number one), singing and laughing, enjoying the fluffy warmth of my doona - things like that. simple, calming and very natural stuff.
Mental relief. this could be in the form of councelling/adressing issues, having a discussion during the day with any issue that concerned me at the time, mediation, breathing/visualization exercises, having fun etc. having this during the day really helped the night time process.
Some of the other things that helped included:
creating a good environment in the bedroom which didnt have noise or light that disturbs/distracts you. And getting rid of the clutter and 'electrical' stuff.
avoiding/limiting caffeine, alcohol or any other sort of drugs.
having your evening/last meal early.
eating a wholefood/rawfood diet. at least getting rid of the sugary/wheaty/animally/MSG/drug tainted processed stuff.
accept that the last part of the day is purely about your pleasure and peace - not organising, thinking, tv etc etc. I used to be a chronically busy person who needed to fill every moment and do things rather then just 'be'.
stretching (not the 'stimulating' poses though) around bed time.
and of course, a very big cuddle from the one you love who loves you back. (man, pet, whoever).

hope something above helps, these are all the ones that worked for me.
