What this calculator will compute
Inputs: caffeine dose (mg), time of consumption, personal half-life (hours) and target bedtime.
Outputs: caffeine remaining at bedtime (mg), time to a chosen residual threshold and decay curve.
Formula, recorded as scope and not yet verified against a primary source: First-order elimination: C(t) = C0 * 0.5^(t / t_half), with a population mean half-life of about five hours in healthy adults, extended to eight to 10 hours during oral contraceptive use and to more than 15 hours in pregnancy, and shortened in smokers by CYP1A2 induction.
