According to www.preceden.com, energy drinks have been around since the 1960's, but weren't introduced to the United States until the late 1990's.
Since then, caffeine-laden drinks have exploded in popularity.
But so have the side effects.
"Most of the time when I first enter work I'm really tired and really sleepy so then by the time I drink my energy drink I feel a little bit better," said Janelle Marjaniemi.
Janelle Marjaniemi says she drinks one to two eight ounce cans of energy drink about five days a week.
She says she needs to be up for work by 5:30 every morning, and needs the boost the drink offers.
"I probably started when I started my job, with all the early hours and just needing it. Kind of feeling like you need that little bit of preparedness for the day, so I'd start with those," said Marjaniemi.
John Naracon has some liquid energy when he needs a pick-me-up before or during work as well.
"If I've had a long weekend at work or whatever and not a whole lot of sleep and I've got to get up early the next day to get back to work, I'll grab one or two to get me through the day just to give me that extra boost," said Naracon.
And they're not alone.
But there's a problem.
"What happens is it keeps dehydrating your body, so you never kind of catch up. So you can have fatalities. And the hospitalizations are rising with these things and actual deaths because people actually die from drinking these and not realizing the harmful effects," said Michele Boehmer, Registered Dietician at Marquette General Hospital.
But dehydration is not the only issue energy drinks cause within your body.
Boehmer says cardiac arrest, high blood pressure, migraines, and even aneurisms are all side effects caused by energy drinks that have sent over 20,000 Americans to the emergency room annually.
Other side effects can include palpitations, shaking, gastrointestinal upset, chest pain, dizziness, numbing or tingling skin, insomnia, and the list goes on.
"Not only do they have the caffeine but they tend to put a lot of B-vitamins in them and a lot of additives,
which is not regulated. And so you can actually get too much of a good thing," said Boehmer.
And the caffeine dose is huge.
A normal cup of coffee has about 200mg, which one would normally slowly sip.
But an energy drink, which one drinks quickly, can have anywhere between 160 to over 500mg of caffeine.
A maximum daily dose for an average adult in good health is no more than 400mg.
"To be honest, I would never suggest an energy drink because they're not regulated. They typically have too much vitamin B," said Boehmer.
Boehmer says it is okay to have an energy drink on occasion.
However, she says you should never mix alcohol and energy drinks, such as a popular drink that combines Red Bull and vodka.
She says it's a deadly combination that you should never try.
Also making headlines is the energy shot, 5 Hour Energy.
FOX News says the Oregon Attorney General has recently filed suit against the makers and marketers of 5 Hour Energy.
They say it falsely claims customers get extra energy and focus from a unique blend of ingredients, when the effect actually comes from a concentrated dose of caffeine.
