Latest time to drink it

For an 11 pm bedtime, most people should finish a 16 fl oz can of 3D Energy by about 12:30 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	5:30 am	10:30 am	3:30 pm
10 pm	6:30 am	11:30 am	4:30 pm
11 pm	7:30 am	12:30 pm	5:30 pm
Midnight	8:30 am	1:30 pm	6:30 pm
1 am	9:30 am	2:30 pm	7:30 pm

For a 16 fl oz can of 3D Energy, 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 a 16 fl oz can of 3D Energy peaks in your blood about 75 minutes after you start it, at roughly 171 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	140 mg	93 mg	61 mg	40 mg

So one had at 3 pm leaves about 70 mg at 11 pm. How long caffeine lasts explains the curve.

Method and limits

The caffeine figure comes from 3denergydrink.com; 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.

These are estimates for information, not medical advice. If you are pregnant, ask your doctor; common guidance is under 200 mg a day.
