Is it bad to drink four or five rockstar energy drinks daily?

Is it bad to drink four or five rockstar energy drinks daily? I really like them, I know they can't be good for me...but they do have some herbs like guarana, etc, so they can't be 100% wrong. Would it be bad to drink like four or five of these daily?...

Worse, or better than drinking a similar amount of coca cola daily?

There is nothing wrong with it. It does have an incredible amount of sugar and caffeine, though. So if you are sensitive then you might want to cut down. I drink about six rock stars a day myself.

They can't be that good for you, honestly. From reading this discussion: http://www.funadvice.com/q/... they sound like they might be a bit worse than coffee.

o wow let me know if you figer that one out because I do the same

I think I have drank so many of them that your system becomes ammune to them nothing happens to me anymore I used to get jittery but now I just feel awake and I drink sometimes 4 or 5 a day

when you consume that much caffeine daily you increase the amount of adenosine receptors in your body. Adenosine is what makes you feel tired, and caffeine blocks adenosine making you not tired. However, with the increase in adenosine receptors you are more susceptible to adenosine. Complete tolerance to sleep disruption effects of caffeine develops after consuming 400 milligrams of caffeine 3 times a day for 7 days.
Rockstar contains 140 milligrams of caffeine per serving (2 per can) and 200 milligrams of guarana per serving (2 per can), which is caffeine from the the guarana plant. So that is 640 milligrams of caffeine per can. So 1 can a day is enough to cancel the effects on tiredness of caffeine. Caffeine does not actually give energy it only temporarily reduces the effects of tiredness.
Caffeine is not all bad though, it does improve brain and body functionality. The optimal dosage of caffeine is about 9 milligrams of caffeine per kilogram of body weight. It takes 3 to 4 hours for these levels to reduce to half in the body.
