Track the caffeine. Then see what it is doing to the rest of your day.

Two 200 mg days can be completely different. One might be a morning coffee before an easy run. The other might be 100 mg at breakfast and another 100 mg late in the afternoon before a night when sleep duration, HRV, and resting heart rate all move the wrong way. A daily total alone cannot show that distinction. Dose timing can.

That is why caffeine belongs in the same health timeline as sleep, recovery, training load, nutrition, and wearable data. Wellness Project gives Max, Casey, and your connected AI assistants the actual history so they can answer questions about your pattern instead of guessing from a generic caffeine rule.
