6. Tea: Herbal teas are great for people who have problems with sleep. Make a mug of decaffeinated tea and drink it in the evening. You can try out various herbs like chamomile or passionflower. Some prefer valerian and mint teas. All these herbs have a soothing and sedating effect. A bit of honey will enhance the effect since this sweet treat contains tryptophan. Avoid herbs that are known for their stimulating properties like ginseng tea.
