Yes. I don't care how completely stupid this sounds, but years ago it took me about 2 solid weeks to recover from jet lag and it got me thinking to never traveling again. Then, I met a couple in Copenhagen who swore by this, and have been using ever since. I cannot sleep on airplanes (although I've tried plenty of times) and now, I just bring these. Originally purchased at Whole Foods but you could probably find them anywhere. Don't leave home without them!

And yes, the last trip was I think a 13 hour flight plus a layover in DC and I was mega-stressed because of an external matter. My friend traveling with me didn't have the same "belief" that I had in these dopey little pills but ended up without jetlag regardless.
I know, it sounds stupid. Whatever. Works for me!!!!
