Are there any longterm side effects from drinking energy drinks?

I'm 46 and have been drinking caffeine since I was old enough to keep both ends off the ground. I used to drink 7-9 cans of Mountain Dew a day. Never bothered me UNTIL I hit 40. Then developed arrythmia, while I can't prove it's the caffeine. I'm one of nine kids and I'm the only one that has it, so it's not hereditary, and other than caffeine, I can't think of what would cause it.

One or so a day I wouldn't think would hurt, just try not to go over board, you might regret it later.

Yes. Even if you are active 24/7, energy drinks are still bad for you. I'm not gonna pretend to know specifically why they are bad, but there is a reason why people tell you not to drink them. I'm not a doctor, but I guess this is better than nothing.

i am not sure but don't drink them too much, my husband drinks them all the time and before they would wake him up now after he drinks them he falls asleep. those can give you diabetes and many other health problems. Just drink them when you trully need then and don't tell me thats every day because if thats the case you just need a vacation to energize.

Judging by the amount of chemical intake ure getting everyday-probably!

It can cause hypertension (high blood pressure) and other serious health problems even death in some cases.

Noooope, ive been drinkin them 4eva and Im juuust fine!!! hehe ;)

i heard a long time ago that they would shrink your dink. But i dont know for certain....lol. i guess only time will tell.

I think you'll be fine as long as you burn all that extra energy

None that have been studied.

well, pretty sure it can affect your heartbeat.
