All energy drinks are crap in my opinion. They have plenty of sugars and caffeine. Health wise they aren't good at all, save the fact they do provide a good source of various vitamins commonly lost by sweating and dehydration. Or simply improper nutritional intake. If you eat healthy there really isn't any need for such drinks and you can get a caffeine burst just by drinking regular coffee, taken black. (thus avoid excess sugars). You can buy vitamins in large quantities and they are more a balanced source of all vitamins. Like many so called energy drinks, protein bars etc..its junk food masquerading as health food. A unsweetened whole grain cereal with milk would be far more healthier and lower in calories and sugar than those energy bars etc.
Maybe look into eating a healthy diet and find other ways to relief stress than mass drinking energy drinks. A glass of water and having vitamins once a day will work far better for you, plus regular exercise etc.
