I've had severe insomnia my entire life - I miss at least one night's sleep a week, often pull overnighters, etc. My mind just won't shut off, or it will but despite being exhausted I am not sleepy. I started exercising daily and meditating at least half an hour a day and now I sleep like a baby. Sometimes it takes a couple hours of reading, but its not a severe problem for me anymore. Exercise or meditation alone didn't do it. Together they give me physical tiredness and mental quiet, which means sleep. Its amazing what physical/mental upkeep will do for you. That being said... I just install F.lux and may try some of this other stuff too!
