A friend of mine recently had a week of feeling headachey and tired. She wondered if she might have lyme disease until she realized she was accidentally drinking decaf instead of regular coffee. Meanwhile, a patient of mine had an intense uptick in anxiety & waking up in the middle of the night in a panic. The only change? An increase in caffeine consumption. Another patient was having an increase in migraines and weird vascular phenomenon. The reason? Shifting from coffee to tea.
Whether you drink coffee or espresso or tea or soda, aim to keep caffeine consistent day-to-day. Same amount, same time. When you deviate, you might experience symptoms like anxiety, panic, insomnia, fatigue, headaches, or irritability. If this happens, remember to attribute it to the caffeine discrepancy, and not that everything is terrible.
Personally, I’m so exquisitely sensitive to caffeine that I decided to go 100% caffeine-free. While I miss coffee, I realized I was frequently overshooting or undershooting caffeine, and zero is a number I can achieve consistently day after day.
