Get into a bedtime routine – something that allows you to wind down, and to signal your body that it is time for sleep. Keep to that routine, and eventually your body will begin to heed those signals. It could be an evening hot soak in the tub, or curling up with a good book for a while, maybe sipping warm milk, chamomile tea or a glass of wine. Whatever the routine, make it restful. Nothing stimulating here!
