Ask HN: How do you force yourself to take breaks while coding?

I'm a dev with zero self-control. "One more function" turns into 3 hours.

Tried Apple Screen Time – I just click "Ignore" every time. Tried Pomodoro apps – closed them when they got annoying.

What actually works for you? Hardware timers? Standing desks? Blocking software?

I'm building a macOS tool that uses full-screen overlays with a 30s cooldown to bypass, but curious what approaches others have found effective.
