More than Insomnia I used to have sleep patterns where my mind wouldn't quiet down. After I started practising meditation, specifically the 8 point "Passage Meditation", I started experiencing a much better quality of sleep. http://bmcm.org/

For those who do not have time for meditation, you may find the second point called Mantram (repetition of holy name) useful: https://www.bmcm.org/learn/mantram/
