Is there really anything bad about energy drinks...? Besides of course the obvious that there's a lot of caffeine? I eliminated Soda from my diet, pretty much completely and have been off of it for 2+ weeks and don't plan on going back. However, in the morning i'm extremely tired and I dont like the taste of coffee and have been drinking rock stars sugar free (no carb if it's available, i think it tastes better). I read somewhere online that you shouldn't drink more then 400mg of caffeine, i only drink one a day in the morning to wake me up and it has 160mg (with 2 servings). Is it really that bad for you...? If you drink energy drinks what do you drink?
