To those who constantly fly, how do you handle jet lag?

I don't even feel It tbh , I just take a long nap

When I traveled all the time and had to adjust to the new time, I would find a place where I could swim, and get myself tired enough to sleep for at least 4 hrs (alarm), no matter what the local time was..

I don't, but if I did, I would use melatonin. It works wonders for this shift worker.

Don't feel it. I usually bring my vita when I take trips so I'm too distracted to notice.

I don't handle it well anymore..I take melatonin when it's time to sleep.
