Unfortunately, I've seen some people get burnout that really sticks. Some found success with a much longer break (3 weeks - 6 months). I've also heard that certain types of talk therapy can unravel the burnout drivers, so one can address them "on the fly," without interrupting work too much. Finally, something else may be going on, so you may want to check in with your personal doctor or a psychiatrist. For example, a hidden vitamin deficiency can do all sorts of wacky things to quality of life.

I can confirm, a couple months long break always does wonders for me. That's why I prefer to be a contractor, as such breaks are not compatible with full-time employment.

I sure do miss contractor life right now.

Thanks for the advice! I'm due for an annual physical this month and will be sure to discuss.

At least there is hope that this may not be permanent
