2 teaspoons of Apple Cider Vinegar with a teaspoon on honey in warm water before bed, along with magnesium, niacinamide, tumeric, vitamin C, and occasionally 1/4 teaspoon baking soda. Has helped with lifelong insomnia problem.
Also important is to reduce naps during the day and focus on a quieting image when going to bed. Very important to find a way to calm the mind -- a form of prayer.
I don't expect a perfect night's sleep every night and am usually relieved with the improvement in sleep. Will still awaken after 3=hour sleep cycle but am able to drift back off pretty quickly and sleep till morning.
Am very grateful for the information on this website.
