Drinking coffee is one of the great American pastimes, with some people drinking 10-cups or more throughout the day. Unfortunately, insomnia is also rampant in America thanks in part to this, and will lead to you feeling lousy and unrested in the morning.
The National Sleep Foundation in Virginia says that caffeine is the most popular drug in the world, and is found in more than just coffee—it’s also in your midnight chocolate run and your favorite sodas. It can block sleep-inducing chemicals during the day, but evening consumption can be bad because caffeine lingers for hours in your system, noted the clinic. It can also cause physical addiction and you can wake up craving it along with other symptoms, such as a headache or fatigue.
