I can vouch for F.lux. Its such an essential tool for me now and I have made it a point to get it on all my devices. Apart from the advantages it has in not disrupting my sleep cycle, I actually enjoy the warmer tones. Even when it comes to home lighting, I have always preferred the yellow shades over the incandescent whites. Never tried melatonin, either stand alone or coupled with 5-HTP. Let me read a little more. Thanks for the pointers.

As an aside, I would definitely say get your sleep cycles right and more disciplined definitely puts you in a much higher efficiency bracket. Coupled with some simple lifestyle hacks ( playing a team outdoor sport, if you are not the workout type, no devices in bedroom rule, boring but informative tech talk to go to sleep, light and early dinners, no coffee post sunset) you would be surprised how many extra hours of high concentration work you are capable of.
