Good luck with whatever you decide! I took a year off, but it wasn't planned. I quit a job where I was unhappy. I had plenty of FU money (back before I even knew that term,) so I wasn't stressed out at all. I assumed that I'd take a few weeks off, then get a job, simply because that's what I'd always done. But I was still feeling burned out after a few weeks, so I decided a couple of months wouldn't be too bad. And, well, I kept stretching it out and it was more than 6 months before I started to look for work and then another 6 months before I got offered the right position. Having FU money allowed me to turn down a couple of offers I didn't like.
Now that I'm aiming for FI, I realize that that year off set me back, but I have no regrets. I used that time to work on some personal projects that had always previously ended up at the bottom of my to do lists. I learned to cook (at last!) I spent quality time with family and friends, including some who lived out of town. I joined a gym and got into a regular exercise routine. I volunteered at a nonprofit twice a week. I read a lot. It felt fantastic! I also did a few weeks of consulting to earn some extra cash, and I lived quite inexpensively.
At the end of the year, I had new skills, completed projects, a healthier body, a relaxed mind, and a new job that was more in line with what I wanted. I had less in my savings, but not as much less as I'd predicted, thanks to my frugal ways.
If you think you might "waste" that year by watching tv and wallowing in your unemployment status, then it isn't the right move for you. If you're comfortable with your financial situation and you can imagine fun, interesting, and productive ways to use your time off, then it might be worth trying. Also, you might not want to take a year off. It might be that you only need 3 months to reset your frame of mind.
I hope that whatever you do, it turns out great!
