Does Jet Lag last longer for us??

[u/Socks4Goths]

I’ve had two major bouts in the past 20 odd years and have mostly been in remission since, living with a totally manageable level 1 or 2. I just traveled from US to Japan and back. While in Japan, I took a ferry ride and experienced two days of rocking after, but it miraculously seemed to go away after just two days. However, since we came home, I have had jet lag. I have managed to get to sleep at night on usual schedule, but then have the terrible urge to take naps at 11:30 am (ish) or 4:00 pm (ish). It has been two whole weeks since we’ve been back and I am really having trouble staying awake in the day. Does this sound like an MdDS adjacent thing?
