Did setting strict daily boundaries actually help you recover from work fatigue?

I kept convincing myself I was fine because tasks were still getting shipped but taking calls on weekends and working past dinner slowly drained all my energy.

I didn't need a long vacation I just needed to stop letting work leak into my evenings.

Taking a full step back and enforcing a hard no work rule after a specific hour made a massive difference in my sleep and overall focus within a month.

How do you keep small work exceptions from turning into permanent bad habits?
