I work at home on my own projects. I do my runs almost everyday on my treadmill for 25 mins and go to the gym. Recently I discovered how exercising positively influences the brain, the ability to learn and the mood, I've even written about it: http://romansnitko.posterous.com/how-exercise-makes-you-smarter This book I'm talking about in the post also suggested that exercises should normalize the sleep process, but I guess that's the only effect I haven't managed to achieve so far. I also tried to google it, but only found a list of well known advices that don't work for me and posts about such problems in infants.
I've also ordered this book http://www.amazon.com/Promise-Sleep-Medicine-Connection-Happiness/dp/0440509017/ but it would take time to read it, so I decided to ask if someone had similar problems with sleep here and how they managed to defeat them.
Would highly appreciate the advices.
