For the app fiend

Consider S+ by ResMed. If Big Brother met Mr. Sandman, the result would be this gadget. This machine and app ($179.99, at Bed, Bath & Beyond, bedbathandbeyond.ca) measure breathing, sound and light to determine which factors contribute to your best sleep. Bonus: If you need a lullaby, it will synchronize soothing sounds with your breathing so you drift off faster.
