What CoffeeLog does

TrackCaffeine

TrackCaffeine provides general reference information about caffeine. It is not medical advice. Caffeine values are public-source estimates, not exact measurements.

The model: first-order elimination, half-life 5.7 h, sleep threshold 100 mg, default bedtime 23:00. Every number on this site is computed from those constants and the milligram value of the drink.
