When you have difficulty sleeping, factor in the type of light bulbs you are using. Cool white lights have the blue light spectrum which inhibit sleeping. Lamps should use warm white light and not the blue light spectrum. Try using magnesium cream on your legs including behind your knees and the tops of your feet and also the lower back; as this connects to the sciatic nerve and up to the brain so that your body absorbs the magnesium and helps you to fall asleep easily. Keep a tube of magnesium cream on your bedside table to remind you to use it. Read a book before going to sleep to relax your mind and you should find it easier to drift off to sleep.
