Using melatonin properly completely changed how I sleep. I used to have trouble falling asleep and waking up in the morning, so my sleep schedule would drift back to the point where I would be late to work because I was falling asleep at 4am. I followed the advice of this article[1] and got my sleep schedule back on track. TLDR:

* I take 0.3mg at 7:00pm with the goal of falling asleep at 11:00pm

* Redshift always on at 4500k, turns to 2500k at 10:00pm

I still use a screen until the moment I fall asleep, and I probably don't get enough sunlight. However the changes listed are sufficient for me at least.
