Chamomile is good. Lavender aromatherapy. I have suffered from insomnia since I was a child. I have been through everything, and finally had to bite the bullet and get on Ambien CR. Not the best solution, but it was the only next logical step for me.
I'm an insomniac unless I train hard. Have been since early childhood. Long or hard runs/bikes usually, but not always, tire me out enough to sleep well. But the best sleep inducer is swimming in late afternoon or evening. It can be anything from an easy 20 minutes to a grueling 4000 meter workout; doesn't matter---I will be out like a light. You could give it a try if your family life/pool hours allow. My mom swears by chamomile tea but it does nothing for me. Swimming plus a beer after=out within five minutes of going horizontal.
A simple self help technique that I have been practising to get quality sleep and conquer my insomnia is ‘Focusing on breathing’. It reduces the flow of thoughts, calms the mind and relaxes the muscles, inducing quality sleep. The following mode of this technique can be tried when lying in the bed and needing to sleep.
Triple segment mode: Every finger has 2 cross lines, dividing it into 3 parts or segments. Place the tip of the thumb at the top segment of the little finger and breathe three times. Move the thumb to the middle segment and breathe three times. Move to the bottom segment and breathe three times. Repeat the same steps at the next 3 fingers. At the thumb, place the tip of the index finger on its segments and follow the same steps. Then switch to the other hand and repeat the process all over. Continue to practise, switching the hands. When you wake up in the morning, you will be surprised how you slept so well last night!
My problem sleeping was not being able to shut the brain down. Thinking about too many things to get to sleep. A therapist client of mine suggested I make up a story and focus on that when I lie down. Use the same stroy every night. For a while the story will evolve but very quickly it will just be a comfortable place to substitute for all the daily activity stuff that would keep me awake. As stupid as it may sound, it worked for me. I haven't had to do it for years because I retrained my brain to stop all the routine thoughts when I go to bed.
