Latest time to drink it
For an 11 pm bedtime, a 12 fl oz can of Poppi Cola 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 | 5:05 pm | Any time | Any time |
| 10 pm | 6:05 pm | Any time | Any time |
| 11 pm | 7:05 pm | Any time | Any time |
| Midnight | 8:05 pm | Any time | Any time |
| 1 am | 9:05 pm | Any time | Any time |
For a 12 fl oz can of Poppi Cola, 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 12 fl oz can of Poppi Cola peaks in your blood about 75 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 | 19 mg | 12 mg | 8.1 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 Center for Science in the Public Interest; 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.
