Latest time to drink it

For an 11 pm bedtime, most people should finish an 8 fl oz cup of cappuccino by about 6:35 pm. The table works it out for other bedtimes and for how sensitive you are: it is the latest time to start one so that the caffeine left stays under the line all night.

Bedtime	Very sensitive under 25 mg	Average under 50 mg	Not very sensitive under 100 mg
9 pm	11:35 am	4:35 pm	Any time
10 pm	12:35 pm	5:35 pm	Any time
11 pm	1:35 pm	6:35 pm	Any time
Midnight	2:35 pm	7:35 pm	Any time
1 am	3:35 pm	8:35 pm	Any time

For an 8 fl oz cup of cappuccino, average clearance (half-life 5 h), 8 hours of sleep. "Any time" means even one at bedtime stays under the line.

How long it lasts

The caffeine from an 8 fl oz cup of cappuccino peaks in your blood about 75 minutes after you start it, at roughly 73 mg. Half of it is gone in about 5 hours for an average adult; that ranges from roughly 3 to 7 hours, and longer in pregnancy or with some medicines.

Time after	3 hours	6 hours	9 hours	12 hours
Still in you	60 mg	40 mg	26 mg	17 mg

So one had at 3 pm leaves about 30 mg at 11 pm. How long caffeine lasts explains the curve.

Method and limits

The caffeine figure comes from USDA FoodData Central; recipes, brewing and batches vary, so a real serving can differ. The curves use a standard one-compartment model with an average 5-hour half-life and a sleep-friendly line of 50 mg; your own body may clear caffeine faster or slower. How it works has the details.
