For me, switching to WFH is what did it. It turned out a ton of the stress I associated with the job was centered around being in the office - I was being nearly constantly distracted by people and events which had no bearing on me or my job. Working from home for nearly a year now has been a major relief. I now get my job done in about 3 - 4 hours and then basically just hang out near the phone in case it rings, surfing the web or working on hobby projects.
And the best part is that I'm about 30% more productive this year according to the stats. So it's a win-win for everyone.
