Being very much not a morning person, I get a taste of that too when I have jet lag traveling west. Even after the feeling of jetlag subsides after a few days, I tend still tend to wake up earlier for two more weeks or so.

It's a different world and definitely has advantages. However, like you, I'm not sure it's worth the tradeoff of being horribly tired long before my usual bedtime.

In total, I think I still prefer getting up late and sleeping late.
