I liked the book "The Miracle Morning". It basically set a positive standard for the entire day by starting my routine at the same time each morning and devote an hour or 2 to myself. Depending on the day, I would meditate, exercise, do something for myself, etc all before everyone else was awake.
I then tried to set my bedtime the same each night and lay off every possible stimulant you could imagine 2 hours prior: Caffeine, alcohol, smoking, Heavy exercise, Big meal, etc. I also tied in some environmental calming features for the bedroom like aromatherapy, air purifiers, room darkening shades.
