Has anyone detonated their life and gone on a wild sabbatical?

Has anyone hit a particular net worth on their road to FIRE, and decided "I need a break," and gone to travel for 6-12 months? Even if it meant quitting their job/career? Would you recommend it?

I have been daydreaming more and more about taking 6-12 months off to 'reset.' I work hard, in a stressful but stable & well-paying industry, live in a very large, busy, hectic city where everyone is stressed out constantly.

I am daydreaming about backpacking around Asia or going to Japan, buying a van, and living out of it with my girlfriend and dog when she gets her PhD. (in about a year and a half).

It definitively requires me to lose my golden handcuffs job that I wouldn't get back, but I am so burned out that I'm noticing health issues pop up, constant stress, I have half-asleep nightmares about work even (I'm in healthcare).

There are certainly options for when/if I want to return, just none that are quite as good.

Talk me in or out of this. What are your experiences?
