Caffeine dose tracker

Track more than cups. A useful caffeine log captures amount, timing, sleep, and daytime energy so you can identify patterns and taper with fewer surprises.

Core fields that improve decision quality

Total caffeine estimate and source type.
First and last caffeine window each day.
Energy level swings and craving intensity.
Sleep duration and perceived sleep quality.
Notes on stress, work demands, and social routines.

Pattern examples to watch for

If your last intake moves later, sleep may worsen, then next-day caffeine may increase. Tracking this loop helps you choose better leverage points, such as earlier cutoff times or slower reductions.

Weekly review beats daily overreaction. Averages and trend direction matter more than any single entry.
