Plan your days like you're an obsessive
Another way to avoid those late-night stress sessions is to plan your life like crazy when you're actually awake, eliminating your brain's incessant reminders as you drift off that you forgot to write that meeting down. Easier said than done, but there are some simple habits you can start to develop that will make it less of a hassle over time. Make use of your phone's calendar, use a fancy planner, or color code a traditional wall calendar to within an inch of its life. If you tap out or write down things when you schedule them and go about your day, you'll likely have far less to worry about when the lights go down.
Avoid giant meals at night
Sure, it's tempting to eat half a pizza while watching TV in the late evening, but science says that's probably not the best idea -- rich meals late at night can disrupt your normal sleep cycle and can also lead to other unpleasant things, like gaining weight and developing type 2 diabetes. You don't want any of that, and if changing your eating habits can improve your overall quality of sleep as well, that's a win-win for sure.
