A two+ hour drive would really take it out of me. I would often have to stop and have a 10 minute nap.
I’ve found meds have really helped, I still feel tired, but I don’t have to sleep afterwards or take naps.
Same with riding motorbike, but double. I think it’s the intense concentration for long periods of time.
@luthis I also love to drive, before and after I got medication, but when I used to be stuck in rush hour traffic I had to fight not to fall sleep after my workday.
