When people talk about having “a cup of coffee,” they don’t necessarily mean 8 ounces (236 milliliters). For example, many people go for the large size of coffee at McDonald’s restaurants and Starbucks, at 20 ounces (591 milliliters). Or at home, they may have a 12- to 16-ounce mug.
So when you read guides online that say an 8-ounce cup of drip java has about 163 mg of caffeine, you can more than double the amount of the stimulating chemical for a 20-ounce size. Drip coffee is the kind that drips through a filter to produce that cup or mug of the elixir that so many people say they can’t start their day without.
The question is of great concern because in the United States, drowsy driving kills an estimated ~800 people a year in 90,000-some accidents, says the National Sleep Foundation in its article How To Stay Awake On The Road .
The AAA says the numbers are even more alarming than what the NSF announced:
The AAA Foundation for Traffic Safety estimates that an average of 328,000 annual crashes in the U.S. involve a drowsy driver, including 109,000 that result in injuries and 6,400 that involve a fatality. The National Transportation Safety Board also included “reduce fatigue-related accidents” on its 2017-2018 Most Wanted List of the 10 most critical changes needed to reduce transportation accidents and save lives. 
Is getting a caffeine fix really bad for pregnant women?
We’re going to try to answer this million-dollar question by putting together the various research and studies we’ve found on the topic and try to help you ladies come up with not just an answer, but a solution.
The long-term practices are to get a good, healthy diet; sleep on a regular schedule, at least 7 hours a night (or day, if you work the graveyard shift); and exercise regularly to stay physically fit.
The short-term practices are more detailed. And we can all take a hint from truck drivers, who are experts in driving long distances and staying awake.
Underlying both the short-term and long-term practices is judicious use of caffeine. If you rely too much on caffeine, one study finds , you run the risk of crashing. For truckers who get a good, healthy amount of caffeine, another study found , they can avoid crashes and save lives.
For many truckers, the fight to stay awake is a daily (or nightly) one.
You should follow the long-term tips of getting a good diet, exercising plenty, and getting on a good sleep schedule that we at Viter Energy Mints outlined in this blog  to help truckers. Those three strategies, plus judicial use of caffeine, can save lives.
For some short-term tips on staying awake on the road, read on.
Truckers have a way to help save their lives and the lives of others: caffeine. A 2013 study found that truckers who consume caffeine are 63% less likely to crash . The American Association for the Advancement of Science writes:
Long distance commercial drivers who consume caffeinated substances such as coffee or energy drinks, to stay awake while driving, are significantly less likely to crash than those who do not, even though they drive longer distances and sleep less, finds a study published today on bmj.com.
Do you find yourself heading to the coffee-maker straight from bed? Then you’re one of 62% Americans who drink coffee every single day. Call it a morning ritual or a habit that can’t be shaken, but it’s pure unadulterated java love. But are you addicted to it? Here's how you'll know if you are and how to dial it down.
Coffee is the top-of-mind source of caffeine, which is a natural substance that’s considered a stimulant, something that promotes alertness. It can heighten mood and make you happy, improve reaction time, and elevate mental performance. 
Microdosing has become so popular these days – and for all the right reasons. A trend in Silicon Valley, microdosing has a become a common practice of ingesting minimal doses of a substance – say one-tenth or one-twentieth of what’s normal.
The point is to reap all the positive effects of a substance and steer clear of the negative. Microdosing is perceived to boost cognitive functions – such as improve concentration – and increase energy levels.
The practice has been perceived to be so effective that some have repurposed and applied it to caffeine.
Is there a big difference between synthetic and natural caffeine? Which gives a stronger jolt? Does it even matter?
Natural caffeine in coffee, tea, and chocolate is much less common than the synthetic caffeine found in so many other products.
Caffeine is found in plant species such as the more popular ones like Coffea arabica and Coffea robusta, as well as tea leaves, kola nuts, cacao beans, Yerba mate and guarana berries.
Not only does naturally-occurring caffeine from said plants keep your cognitive functions at their peak, but it also contains antioxidants that help you fight illnesses like cancer and Alzheimer’s.
Caffeine is NOT addictive, but it sure is habit-forming. You don’t hear about coffee addicts robbing stores and hijacking motorists to get money for a fix. That’s because while caffeine does cause dependence, it isn’t in the same category as opiates or alcohol.
