I solve that the blunt force way. Heavy duty over the ear hearing protection, like shooters eeesr at a gym range. I find it works better than noise canceling. If things are really intolerably bad you can double up with foam earplugs under.

Bose noise cancelling headphones. Just leave them switched on without music playing. It will actively reduce the noise level.

We could, as a society, ban the use of gas powered leaf blowers.

"I took down prod and accidentally dropped the entire db table of real customer transaction data. But I've got a date tonight with that new hottie from the gym." = Good day.

Try cutting down your caffeine really slowly. I did it by gradually cutting caffeinated coffee with slightly more decaff, over months. Eventually I was 100% decaff. Never had any withdrawal (the headaches, and energy slumps you mention).

And now I no longer have any of the bad symptoms caffeine was giving me: nervous tick, wildly fluctuating energy levels, random extreme emotions.

Back when I was younger, caffeine had none of those bad effects on me. But as I grew older, they started to ramp up. Because coffee was such a constant in my life, it took me many years to realise the cause.
