I’ve been jetlagged once or twice. 
Get as much sunlight as possible during the day. It helps your circadian rythm figure out what the fuck it’s supposed to be doing.
Steady bits of caffein thoughout the day will help too. It takes about a week till you really feel normal. 2 weeks till you’re back into a regular sleep routine, haha if you had one.
And yeah, as leetsauce said, don’t try to force your body into complying. Naps are fine.
