Latest time to eat it
For an 11 pm bedtime, most people should finish one piece (175 g) of tiramisu by about 9:20 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 | 2:10 pm | 7:20 pm | Any time |
| 10 pm | 3:10 pm | 8:20 pm | Any time |
| 11 pm | 4:10 pm | 9:20 pm | Any time |
| Midnight | 5:10 pm | 10:20 pm | Any time |
| 1 am | 6:10 pm | 11:20 pm | Any time |
For one piece (175 g) of tiramisu, 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 (175 g) of tiramisu peaks in your blood about 75 minutes after you start it, at roughly 51 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 | 42 mg | 28 mg | 18 mg | 12 mg |

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.
