You might go to a health food store. Thee is a valerian comination. I can't remember the other herbs but I took it for several years and it worked longer than perscription sleeping pills or tranqualizers which I also find short acting because I build tolerances quickly.
Currently I use actifed and that seems to work faily well.
I also have trazedon (I probably misspelled the name). I notice a few posters use it. I have taken it but find that I have to sleep it off or I feel really hung over. As far as I am concerned its one of the worse things to take for sleeping (or depression which is its main function).
I have had a lot of experience with sleep aids, both over the counter and prescription since I too am an insomniac. There is no clear cut answer. Just try the over the counter stuf until you find one that works if you can.
I wasn't much help because insomnia is related to a variety of differrent problems like stress or depression.
Good luck
