I figured out my sleeping problem was stress/anxiety. I would be thinking about whatever argument I had had that day, or perhaps something I was dreading about tomorrow. I took up reading before bed (fiction! Don't try to be productive by reading textbooks!). Focussing on a story for 20-30 minutes really helps me cache-evict all the stressors that keep me awake. I also stopped programming after around 8pm or so. If I programmed later than that I'd still feel wired at bed time. I'm also trying spending a little more time in single-player games rather than multiplayer. There's something about constant racial slurs over chat, mic spam and general toxicity - it seeps into my mood and I wish I'd realised it earlier.
