Common questions
When should I stop drinking starbucks tripleshot before bed?
For a 23:00 bedtime at standard sensitivity (50 mg bedtime limit), finish your last starbucks tripleshot by 12:09 PM. Sensitive readers should shift earlier; tolerant readers later.
Why do the times differ so much between people?
Caffeine half-life ranges 1.5–9.5 h across healthy adults, and dose differs by drink. The same can that clears a fast metabolizer by dinner can still be 50 mg in a slow one at midnight.
Method
Cutoff = bedtime − T½ × log₂(dose ÷ limit), base T½ 5 h, limits 25/50/100 mg. Every cell is computed, not quoted — the cutoff calculator applies the same formula with your metabolism factors.
