I only use them when preparing exams since I don't drink coffee. It helps me to stay up all night. Most of the time I drink red bull or guarana(local energy drink).
you know how much sugar are in those stupid drinks? my freinds dad died of a heart attack by drinking to many of those, and he only drank one a day, AND had no previous heart problems, plus he was only 39, and the doctors even said it was due to the caffine. i guess they would be ok if you drankin VERY LARGE moderation.
There are a few drink manufacturers who offer diet versions of their drinks, with sucralose and Ace-K instead of sugar. I actually drink one made with those sweeteners that has 0 carbs, 0 sugar, 8 calories, and 4900% of your daily B12.
I doubt energy drinks were the only contributing factor in your friend's father's death. They may have set off a reaction to a heart condition no one knew he had.
