2. Microdosing Caffeine

Instead of my usual oversized mug of coffee, I experimented with microdosing caffeine—consuming tiny, controlled amounts throughout the day.
The effect was surprisingly different from a traditional caffeine jolt. My focus sharpened without the usual crash or jitteriness, but I also noticed a subtle undercurrent of anxiety that lingered.
According to scientific research, small doses help maintain alertness while reducing side effects.
Still, the delicate balance between clarity and anxious energy was more noticeable than I’d expected.
