Gosh yes. The level of stress I had in customer-facing work was astronomical, especially in-bound calls and queries 7 hours a day. I could do it, but I was so wrung out by the end of it, my nights were spent in an exhausted haze.

My current job is in a quiet office where I manage the workflow and I get maybe 2-3 queries a day, if that, and I'm still able to do stuff I enjoy in the evenings :) Work no longer eats all my mental battery.
