People get used to most things. A few weeks after winning the lottery or losing an arm, they are mostly as happy as they were before. (Mostly! Not completely.)
But I read somewhere that the misery of commuting is strangely resistance to the hedonic treadmill.
I suggest you look up more recent research on the hedonic treadmill and winning the lottery and losing a limb specifically. I’m very confident winning the lottery durably raises life satisfaction and that it takes years, not months for losing a limb to be mostly but not entirely gotten over.
Entirely resistant if I remember correctly. You don’t get used to commuting, you forget what it feels like not commuting, like you don’t get used to feeling like crap because you don’t exercise or are sleep deprived, just forget what normal feels like.
