Latest time to drink it

For an 11 pm bedtime, one piece of Neuro Gum stays under the 50 mg most people sleep fine with, even late in the evening. 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	5:10 pm	Any time	Any time
10 pm	6:10 pm	Any time	Any time
11 pm	7:10 pm	Any time	Any time
Midnight	8:10 pm	Any time	Any time
1 am	9:10 pm	Any time	Any time

For one piece of Neuro Gum, 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 one piece of Neuro Gum peaks in your blood about 70 minutes after you start it, at roughly 34 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	28 mg	18 mg	12 mg	8 mg

So one had at 3 pm leaves about 14 mg at 11 pm. How long caffeine lasts explains the curve.

Method and limits

The caffeine figure comes from neurogum.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.
