Does anyone have a sure-fire way to cure insomnia?

Hi…My sleep schedule is completely out of sync. I am sleeping strangely odd hours and not regular hours. I worked nights for years and feel that this contributed to this wake/sleep pattern. I was doing okay, but in the last three weeks am just not able to sleep regularly and it is very, very frustrating.

I took a natural supplement (it did not work). I took an over-the-counter supplement and that did not work. I get a little bit relaxed, but not enough to sleep . I’ve tried camomile tea, I exercise every day (have for years) and even that doesn’t help. Hot showers or tub baths don’t help either. Neither does playing soft music or no music.

Does anyone have a recommendation? I welcome any folk remedies, allopathic remedies, natural remedies, whatever worked for you….anything. Just send recommendations. I am at the end of my rope..or..er…sitting on the edge of my bed.

Thank you so much!
