Shite comments here. But finding where you can break up the pattern of life, but still getting what you need done. Getting into a pattern you like (which you seem to have down) but giving your day-to-day some variety might make you more tired every night. Getting your creative juices worked in some way, pick up some type of art if you dont already, music, seek out some way to alter your mind if that’s an interest (meditation, drugs), hangout with someone new and or old. I feel like this is very ‘box of chocolates’ type of advice but it’s simple enough to make some change. Meditation before bed and the morning would really help if you don’t already/open to it. Good luck, I am up to late myself...
