I have insomnia. It comes and goes, but when my insomnia is in full-swing sleep is virtually impossible for me. I have my own little routine that seems to help, however. Turning off all the lights relatively early, getting into my comfy clothes, and gradually winding down over a period of hours. Whether you're a long-time insomniac like me or you've just been tossing and turning as of late, this site has good tips for getting your zzz's.

1. Stick to a schedule. Even on the weekends, it's a good idea to go to sleep and wake up at about the same time.
   
2. Create a ritual. Follow a routine that helps you unwind and prepare for sleep.
3. Turn everything off. Turn off lights, radios, TVs, even clocks that may interfere with your rest.
4. Create a safe haven. Create a relaxing environment -- clutter free, calming colors.
   
5. Get comfy. Fluffy pillows, soft blankets, and comfy pjs can help you get a sound night.
6. Watch what -- and when -- you eat. Avoid sugar and other unhealthy food in the evenings and don't eat anything within two hours of going to bed.
7. Get moving. Exercise throughout the day and also 3-4 hours before sleep can help you get more rest.
8. Use your bedroom for sleep (and sex). Your bedroom isn't a second living room. Keep laptops, work, and other items out of your bedroom. Your room should be a place of relaxation -- not another source of stress.
9. Try guided imagery. There are CDs designed to help you relax. (Side note -- this one sounds a bit loopy to me, personally... but to each his own.)
10. Avoid nicotine, alcohol, and caffeine. All three disrupt your sleep and aren't health-promoting (for the most part) anyway. Just one more reason to avoid them.
    
11. Get plenty of daylight. Melatonin and some other hormones are triggered by daylight. Spend time outdoors during the day and keep your bedroom as dark as possible at night to balance hormones and help yourself sleep.
12. Write it down. If you tend to worry and replay the day's events when you're trying to sleep, try writing everything down in a journal before going to bed. Getting it out on paper may help you avoid worrying about it later.
