Caffeine may be present in a wide variety of foods and beverages, including coffee, tea (both black and green), chocolate, energy drinks, soft drinks, weight loss supplements, kola nuts.
Even certain prescription medications, such as those for headaches or colds/flu.

Caffeine’s effects wear off after a certain amount of time
Caffeine has a rapid onset of action in the body. 30-60 minutes later, it reaches its peak in your bloodstream.

What is the effect of coffee on sleep?
When it comes to sleep, caffeine has been shown to have an impact on both quantity and quality.
A lack of sleep might result from it. Some research has shown that consuming coffee at least six hours before night reduces overall sleep duration by one hour.
Coffee also has the effect of making sleep less restful and decreasing the depth of sleep.
It also makes you more prone to nighttime awakenings, resulting in a more disjointed sleep pattern.
In addition, it has the potential to throw off your internal clock.

Coffee may do the same thing. Adenosine, on the other hand, activates these receptors.
When you have a cup of coffee before bed, it prevents the effects of adenosine and keeps you up and aware instead.
