For nearly two years as a software engineer, my mind drifted constantly during long coding sessions. Mid-afternoon mental fatigue made finishing complex logic problems frustratingly difficult.
I restructured my workday into dedicated forty-five-minute sprint blocks followed by brief walks. I cut out late-afternoon espresso, replaced it with peppermint tea, and started doing cold water splashes on my face between tasks.
Over time, I felt my concentration stabilize through the entire afternoon. My personal experience was a much smoother coding flow without mid-day brain fog.
