I think Spartana will have some interesting insight...IIRC, she took a sabbatical and never went back.
I'm FIRE now, but hated intensely disliked certain aspects of my job before I finally pulled the trigger. Here are some coping things I did. First, I set a crazy high savings goal for one year (you can select any length of time for yourself). I literally spent aslittleaspossible in every single category. No new or used anything, unless it was absolutely essential. Ate down the pantry, used u my supplies, grew my hair long, brown bagged every meal, etc. When it got tight and I was going stir crazy, I spent unused gift cards and traveled via miles to places I could stay free. Watching the savings grow really helped me cope. At the 90-days-to-go mark, I made a colorful paper chain and festooned it around my office. I knew what it represented, but no one else did. At the end of every day, I removed a link. I loved Mondays, cause I got to remove three links, woot!
Obviously, my vote is to set a time limit for yourself, save your brains out, and then pull the rip cord for a fast and long-lasting, perhaps even permanent, exit. And don't stress to much about trying to mold yourself to the job. Don't worry about changing it or making it fulfilling either, 'cause you're not going to be there long. Make it work for you, not the other way around. Good luck!
