What works for insomnia?

A dear friend is suffering badly from insomnia, unable to get a full night’s sleep without taking something. She is exasperated by chiropractors who say they can help her, take her $200, and she’s still not sleeping.

I would be too.

I had one period a few years back when I didn’t sleep well for months. I remember how dreadful that was. I felt tired, cranky, and tense all the time. I tried supplements, which weren’t very effective. Listening to a delta brain wave CD helped, but it required falling asleep with headphones on, which was awkward.

Eventually something shifted, and I slept well again.

If you have any experience or have heard of effective remedies for insomnia (that don’t include pharmaceuticals or Benadryl or anything OTC with “PM” in the name), would you mind sharing in the comments?

Thank you.
