You may experience caffeine intoxication
Taking too much caffeine can result in severe caffeine intoxication, a condition that causes you to experience things such as vomiting, seizures, increased heartbeat, and more. And while you can experience this from taking any source of caffeine, your chances of experiencing these effects are higher with energy drinks considering how much caffeine some of them contain.
You may experience heart trouble
Red bull energy drinks and Shutterstock can have this effect. Irregular heartbeat is a major concern for regular energy drink consumers and general caffeine consumers also. Therefore, if you are taking an energy drink with excessive amounts of this stimulant, you may notice your heart beating in a pattern that you have not experienced before.
