There are herbs can can help you relax and help you to sleep, eg, valerian root, kava kava, chamomile, hops, passion flower, skullcap. Probably, valerian root and kava kava are the best. You have to keep in mind that it can take a few weeks for some herbs (including valerian) to build up in your system before they start to work.

You can also try 5-HTP, trytophan, GABA, or melatonin (about 3 mg). I would not take melatonin for over a month unless your doctor says it is ok.

Over the counter pills include unisom, sominex, benadryl, tylenol PM, advil PM, etc. The pharmacist might have the best ideas.

I once wrote a long list of natural sleep aids and have copied it below. It is so long that reading it may put you to sleep :=)

A warm bath is a great way to relax to help you to sleep. If you can’t take a bath, you can give yourself a foot massage with slightly warm massage oil, sesame oil, or castor oil from a health food store.

What was very helpful to me, especially when my mind was racing, was to lie in bed and listen to relaxation CDs, especially those that contain someone speaking with relaxing music in the background. Many of these CDs are available on eBay for very low prices.

A helpful technique is to relax your body one part at a time. So you could relax your feet, your lower legs, upper legs, moving up from your lower belly up to your chest, etc., until your whole body is relaxed.

Of course, guided relaxation methods can help, imagining yourself in the country, the beach, or whatever is most soothing to you.

If you have annoying thoughts or personal issues that run thru your mind when you are trying to sleep, you might have to deal with those issues first.
