Do energy drinks really keep you going during the day?
user
It’s important to realize that energy drinks aren’t a replacement for healthy eating and regular sleep.  The theory behind their efficacy is that caffeine is a stimulant which can provide extra energy, but there’s no clear evidence that drinking an energy drink is actually better for you than having a normal cup of coffee.  In fact, excessive consumption of caffeine is likely to cause common side effects including sleep problems, nervousness, and heart palpitations.
