> I found that I worked more, worked more at overtime hours and have been more stressed out than usual.

Here's how I deal with this:

The work computer lives in my office, which I close up and leave at the end of the work day. None of my other devices have access to work email, and none of them receive any form of work related notification ever.

If you ping me about something after I've signed off for the evening, you'll get a response in the morning after I've had my coffee.

Everybody else is free to work around the clock if they like. If they need me, they can catch me while I'm at work.
