Whether you’re dealing with the on-site logistics of an annual conference or you’re shuffling between meetings in your office, your caffeine fix may be one of the key ingredients in determining the success of your day. You don’t want to overdo it, though; the Mayo Clinic recommends a maximum of 400 milligrams of caffeine for adults. After the 400-milligram threshold, you’ll see a number of not-so-positive effects including insomnia, irritability, stomach issues and muscle tremors.

While Red Bull may give you wings, the caffeine in this drink isn’t going to cause serious issues. An eight-ounce can only contains 80 milligrams of caffeine. Translation: five Red Bulls equals one and one-half tall cups of Starbucks.
If a can of Coke is your afternoon-pick-me-up, you’re keeping your caffeine levels in check. In fact, one can only contains 34 grams of caffeine.
