It's recommended to stop drinking caffeinated coffee six hours before bed, according to Schlichter and this study that appeared in the Journal of Clinical Sleep Medicine.

Caffeine's Stimulant Effect And Adenosine
Most of the stimulant effects of caffeine are from its action on the chemical messenger adenosine. Adenosine is released from nerve cells and binds to specific receptors throughout the body. When this occurs it has a sleep-promoting effect.
So in the morning, 9 to 11:30 AM. In the afternoon, between 1 and 5 PM. These periods between natural cortisol boosts are the times where that caffeine jolt will be most productive. Instead of crashing between peaks, you'll maintain alertness.
The sleep disruptive effects of caffeine administration at bedtime are well documented. Indeed, caffeine administration has been used as a model of insomnia.

Why do Italians drink coffee after dinner? “The espresso after dinner is ordered only if the meal was heavy, and they also 'correct' the espresso by adding grappa, known as 'the corretto,'” Milos says. The habit might also have to do with the fact that Italians stay up later.

This tradition has its origins in the ancient Italian coffee roasters, in which water was served to customers before they tasted the coffee. The roasters, in fact, wanted customers to appreciate all the aromatic nuances of coffee without having the taste of other foods previously eaten.
Caffeine — in a travel mug, Hershey wrapper, or mid-day Coke — is a natural stimulant that boosts dopamine production in the brain. This helps to explain why so many adults with ADHD say they couldn't live without it.
Caffeine doesn't target ADHD symptoms as effectively as proven prescriptions. And caffeine plus medication “can result in dangerously acute jitteriness or out-of-control impulsivity,” according to CHADD, a national resource for children and adults with ADHD.
Caffeine interacts with a molecule in the body called adenosine , which assists with communication between brain cells and acts as a nervous system depressant. Adenosine levels increase throughout the day and help promote feelings of drowsiness.
The level of caffeine in your blood peaks about one hour later and stays at this level for several hours for most people. Six hours after caffeine is consumed, half of it is still in your body. It can take up to 10 hours to completely clear caffeine from your bloodstream.

The severity of symptoms vary from individual to individual, and most commonly include a headache, fatigue, decreased energy/activeness, decreased alertness, drowsiness, decreased contentedness, depressed mood, difficulty concentrating, irritability, and feeling foggy/not clearheaded.
The Case for Sipping Coffee Slowly
