Therefore, manufacturers do not have to list specific amounts of ingredients and do not have to follow food/beverage laws.These energy drinks affect many areas of your body, including the cardiovascular and nervous systems, and your sleep. Common side effects: nausea and vomiting, high blood pressure, tremors, dizziness and numbness.
