are they bad for you?? my mom tells me guarana can cause heart attack??

Stay away from energy drinks man they are bad for you.

Evidence?

Just drink water.  You should have enough energy from food, and if you don't, eat more food.  Banana's are excellent sources of energy.  Guarana is a MILD stimulant, so it will raise heart rate and may cause some palpitations, but is very unlikley to give you a heart attack unless you are an 80 year old out of shape overweight man.  Energy drinks are either loaded with sugar or artifical sweetners, both of which are not good for long sustained energy, the former causing swings in blood sugar and the latter causing bloating.  They will not hurt you but are junk and a waste of money.

It is just over use of caffeine that can cause Palpitations.

Yes caffine can cause palpitations too.  But so can guarana.

QFT
 
+ Most energy drinks contain HFCS's, and a boatload of sugar. The diet versions usually contain aspartame, an artificial sweetener arguably worse than sugar.
 
Eat + Sleep proper and your energy levels should be fine, for the extra umph, you could have a cup of green tea.

Yea man, I stay away, they dont seem too effective first of all and give you energy for maybe a half hour but then make you even more tired after that.  Thats what one of my friends claims who is addicted to monsters and sobe adrenalines.  But i dont think they are that great anyway.  Its all up to you in the end though.

you miles well just drink a big glass of sugary pop..........Those things have like wat? 50-70 grams of sugar in them ....THEY ARE LOADED thats horrible for you
