Addicted for YEARS, here is my story...

What helps is to read a book before bed. I'd start at 10:30 or 11. Then make sure you go to bed at the same time everyday, and wake up at the same time everyday. Don't eat too close to bed, and don't have alcohol within 6 hours of going to bed. You'll sleep most soundly between 60 degrees and 67 degrees Fahrenheit. Whatever you do, don't have computer time before bed, computer light speeds up your brain and makes you think a long time before you fall asleep. You can however, sleep with the tv on, or relaxing white noise. If you want code to make your computer shut down after some period of time so you can do this while letting your computer shut down later, let me know.
