Mixing alcohol with energy drinks is an emerging trend in bars and dance clubs. Apart from the dangerous effects this combination may have on cardiac function, people who ingest large amounts of caffeine (a stimulant) along with large amounts of alcohol (a depressant) may not realize the degree to which they are intoxicated. One study noted that participants who consumed energy drinks with alcohol felt fewer symptoms such as headache, weakness, and muscular coordination but were still impaired in terms of motor coordination and visual reaction time.^[44] As many people may use the physical symptoms they experience to gauge their sobriety, the danger is that they may misinterpret their level of inebriation and attempt to drive a car or perform other potentially hazardous activities
