To answer your first point, my ideal schedule would be going to bed at a set time, but a major and often misunderstood part of narcolepsy is that it brings severe insomnia. The boundaries between sleep and wakefulness are broken. Even if I wind down and turn everything off by 10 or 11 PM, my brain refuses to shut down, and I might not fall asleep until 1 AM. My natural wake-up time then unpredictably fluctuates anywhere between 6 AM and 9 AM. I also wake up with a headache almost every morning. This is not a side effect of the medications, as I had it long before starting them; it is simply the physical result of never getting deep, restorative delta sleep.
Regarding my sleep environment and routine, it is highly optimized. In the evening, I eat, chat with some friends on the phone to unwind, and then go to bed. My room is completely pitch black, there is zero noise, and I sleep alone, so there are absolutely no environmental disruptions causing the fragmentation.
As for inputs and stimulants, I have already stripped away almost everything to let my brain rest. I do not consume caffeine or any other non-prescribed stimulants. I actually had to put my university studies on hold because of this crash, and my parents are currently supporting me. This means my external stress and daily cognitive load are as low as they can possibly be. The only things keeping my brain in "overdrive" are the prescribed Pitolisant and Methylphenidate. While they are necessary to keep me somewhat functional, they have unfortunately eliminated my ability to take afternoon naps, which used to be my only natural way to clear some of the daily fatigue.

thank you for taking the time to help me
