Within about 20 minutes you notice your head clear. The mental fog that's been sitting there all morning lifts and your thoughts start moving in a straight line again. Your mood shifts next. You feel calm, motivated, and ready to get after whatever is in front of you. The energy is there but it doesn't feel like caffeine. There's no racing heart, no jittery hands, no anxious buzz. It feels more like someone turned the lights on in a room you didn't realize was dim. That state holds for about 5 to 6 hours and fades gently. No crash, no wall, no sudden drop. You just notice at some point that it's worn off and your day is already done.
