Narcolepsy symptoms eradicated after moving out of the US back to my home country?

I’ve been diagnosed with N1 along with other autoimmune and mental disorders (anxiety, ocd, pcos, ed...). I’ve had SEVERE symptoms since I was in middle school after a flu vaccine, diagnosed around when I was 14-15…

I was initially prescribed Concerta and Vyvance, then neglected when bad side effects showed which led to an autoimmune disorder and worsening of fatigue (as well as other Narcolepsy symptoms). Since then, I’ve tried Provigil, Modafinil, Xyrem, Xywav with and without SSRI’s back and forth for over a decade… the only thing that’s ever helped a bit is the sodium oxybate but even those stopped working after it started giving me uncontrollable eating habits in between dosages (or just second doses never working right).

Anyways that’s pretty much the background of my condition… but ever since I’ve been back to my home country away from where I was in the US, my sleep disturbances have been absolutely non existent. I’ve had one or two cataplectic moments the first week or two, but I’ve been feeling like a normal person since then, and I don’t say that lightly. Been falling asleep almost the same time every day, waking up around the same time for the most part. Napping maybe once or twice a week if I WANT to. I can control my eating habits. I’m not taking any pills or any of that and everything just seems like it didn’t even exist.

Has this ever happened to anyone? I’ve never been chemically tested for orexin or serotonin. I just happened to have all of the symptoms to the highest degree which allowed me to be diagnosed in my initial MSLT. But now I am not experiencing any of them. Even up until two months ago right before I left the states I was having my usual narcolepsy symptoms. With everything I’ve been through for over 10+ years there is no denying that I didn’t have N1. Besides the terrible treatment from one of my docs and neglect from the docs I’ve had, how it has affected my life has been absolutely traumatizing. Is there a chance that my symptoms could’ve been an environmental thing? I am feeling mentally and physically better for sure. This being my home country and the climate being much more favorable for me. Also just other emotional healing I’m getting by being back here. Also lost almost 20 lbs already from having my schedule being consistent. Idk I’m confused but I put it under positivity post because it’s ultimately good news to me.
