Sleep Tips
Because so many people get insomnia, a lot of research has been done on how to beat it. Not all of these tips work for everyone, but one or two might help you:

Write in a journal before you go to bed. This practice clears your mind so you won't have all those thoughts crowding your brain when you're trying to sleep.

Sleep in a dark, comfortable room. Light signals your body that it's time to be awake, so you want to avoid it at night. But if you are really afraid of the dark, it's OK to try a dim night-light. And being hot and sweaty or shivering from the cold can easily keep you up.

Don't sleep with a pet. This can be a tough habit to break, but your lovable dog or cat could be keeping you awake. As your pet cozies up to you or makes noise, it could wake you from a peaceful sleep. Try sleeping without your pet for a couple nights to see if you sleep better that way.

Don't drink any caffeinated beverages (like soda or iced tea) after about 3:00 in the afternoon. Caffeine is a stimulant and might keep you awake.

Don't exercise at night. Keep your exercise to earlier in the day — never within a couple hours of when you go to sleep.

Once you're lying in bed, try a peaceful mind exercise. For instance, count backward from 100 with your eyes closed. By the time you get to 10 (yawn) we hope you'll feel very sleepy. And by 5, we hope you'll feel yourself drifting off ... 3, 2, 1, ZZZZZZZZZZZZZZZZ.
