How long does it take for a cup of coffee to wear off?
When will I become sleepy again?
Answers:
I always have a cuppa coffee before I go to bed. It helps me fall asleep.
But then, I don't seem to have the same reaction most people have to caffeine. I can go without coffee, and not get withdrawal symptoms, and I can drink lots, without getting jittery. The type of coffee also effects how you react. For instance, Espresso coffee actually has less caffeine in it per ounce, than instant coffee. So drinking espresso delivers less caffeine to your system.
Everyone seems to react slightly differently to caffeine. I suspect you need to experiment. Drink a cup of coffee of a specific type, and see how long it takes you to start feeling sleepy. Then drink another type of coffee and do the same.
Then you will know. Everyone else will be unable to tell you exactly how long it will take you, unless they are your identical twin, and they have done this experiment.
Good luck.
Probably in a couple of hours, but it all depends on the person. Some people can hold their coffee for a long time, and not get sleepy, some people get tired immediately, and some people show no side effects of coffee.
