Sound Familiar?
You sleep enough. You eat well. You've tried cutting caffeine. Yet by 2pm the brain fog rolls in, your patience runs thin, and the idea of one more thing on your to-do list feels impossible. You're not broken — you're running on a chronically stressed nervous system.
High cortisol at night keeps your mind racing even when your body is depleted.
Blood sugar and energy dip hard after lunch when adrenal reserves are low.
Chronic stress depletes the neurotransmitters that keep us calm and emotionally steady.
