So the latest news that my condition greatly improved either just randomly or because of increasing iron levels since I began treating my anemia after it was discovered a month ago.

I saw thr sleep psychologist yesterday. She had researched the issue. Anemia can cause a worsening in sleep quality and an increase in sleep need plus extreme fatigue. I stopped donating blood. I last donated in December and would have been due again tomorrow but I have canceled. So maybe it was not narcolepsy after all but anemia. I also got Restless Leg Syndrome and was not able to make my body warm, both consistent with thr iron deficiency anemia diagnosis.

Thank you for the trove of additional info! If I end up needing pharmacological help, I will try these agents.
