Snowdog, nice to see you here at APS.
A couple of folks have recommended OTC stuff like Valerian (which I have no experience with) and Melatonin.
About 7 years ago, I began to have fairly mild (but still annoying) insomnia. A friend and fellow IT guy turned me on to the Melatonin; I have only seen it in dosage from 100mcg (that is, Micrograms) to 5mg (milligrams).
The perfect dosage for me is 3mg, and has worked without fail and without having to titrate upward in 7 years.
I realize your situation may be quite different, but melatonin has worked for a surprising number of folks who (like me)tend to dismiss most OTC remedies as profit generators for their bottlers.
Wishing you the best,

The difference with melatonin is that rather than a medicinal herb, it's something that, if your body is lacking, might result in insomnia. If it has an effect, it's to let your body be able to realize "Ah, it's time to sleep!" and do so.
Valerian is a medicinal herb used as a relaxant for millenia. Yes, it does work. A lot of medicinal herbs do work, but like any compound, a little knowledge is a dangerous thing, and "herbal" doesn't mean "You can take the whole bottle."...you'd still end up in the ER if you did that.
It's just that actual safety studies have shown that while valerian is pretty harmless in the typical dosages, some others, now mostly off the market, like kava-kava, CAN have side effects, especially for people with some medical conditions. And other herbals are downright dangerous, like ephedra, which, though it can act as a decongestant and stimulant, can also raise some people's blood pressure to dangerous or even fatal levels.
As with all things, research is best. Don't automatically discount all herbals, some of them have been used successfully for thousands of years. Others are recently promoted snakeoil.
Generally, if it's meant as a relaxant or stimulant, it has a good chance of doing just that, safety issues varying. Just steer clear of anything that makes any other claims, like weight loss or appetite suppressant. That's just nonsense.
As a side note to that, valerian is DIRT CHEAP, always a good indicator that something is just an herb, not a fad miracle cure of some type. And a wise thing to do with any herb is to try it in a mild tea, first. If you have a violent sneezing fit or find it difficult to breathe, you may well have an allergy to it and would be glad you hadn't injested a full capsule of it.
Caveat emptor. But body-pummeling psyochoreactive compounds from labs, things of unknown longterm bodily effect...aren't always the only solution, IMO. Some of the listed side effects on the commercials for various things ought to set off warning bells. May cause backache, on some... Backache?
The makers of Ambien have a vested interest in convincing you that their $$$ pill works better than a $3 bottle of herb caps. Their profit depends on it.
