I recommend the book "Why we sleep" by Matthew Walker if anyone is interested in the research aspect of what happens when we don't sleep, or don't sleep enough, and the science behind it. I try and not eat after 9pm, stop watching electrical devices 1 hour before bed, and no caffeine after 3pm, and aim for 8+ hours in bed. Im very happy that I can do this, and not have to worry about getting to work on time (I live close to office)
