Fwiw, I put my screen in darkroom mode and use nothing red bulbs in my evening lights.

It's very easy to avoid bluelight while you work. However, as you mention, that's only half the battle.

My issue with this is that warm light encourages melatonin production so I end up dozing whenever I have red light or f.lux/Night Shift/etc on.

It doesn't.

I'd hazard you are sleep deprived.
