Caffeine Intoxication Is A Real Thing

They say too much of a good thing can become something bad.

Ever had a late night espresso that prevented you from sleeping? How about a rapid heartbeat or muscle spasms? According to LiveScience, these are all symptoms of caffeine intoxication. Other symptoms include gastrointestinal upset, rambling speech, extreme fidgeting, nervousness, excitement, redness in the face and restlessness.

While one or two symptoms are normal, it is the combination of 5 or more symptoms including impaired functionality that indicate intoxication.
