Is a five hour energy every day bad for you in the long run?

I would say so: For the most part; any of these "attention getting" products are not very good {short or long term} for you as they usually contain an extreme amount of sugar. If you find yourself having 'energy' problems make sure you start out the day with a healthy breakfast, drink plenty of water, and take a vitamin b complex supplement of your diet is poor.

Caffeine: Many of us use caffeine in our beverages, and that is the active ingredient that helps keep you awake with 5 hour energy drinks.

No long term effect: Used in moderation, there is most likely no adverse effect. Main active ingredient is caffeine. Drinking coffee every days is benign, as far as we know. Sure, you get lots of sugar and maybe artificial color/flavor. No worse than popular soft drinks. Major bad in the long run is cost. People are willing to pay $3+ a day for this, but reluctant to pay same amount for antidepressant.
