Is it possible to experience some form of overdose from energy drinks?

I drank three Rockstar 16oz energy drinks over a four hour period. About fifteen minutes after the last one I noticed my heart was pounding pretty bad.

Then I got twitches. Yeah, TWITCHES. My face and chest and fingers all would just twitch. I felt tingles in my left arm and right leg. Then, like an hour later, I got VERY sick - dry heaves like you wouldn't believe.

Really, I thought I was going to have a stroke or a seizure. I became anxious and thoughts were racing through my head, but I couldn't keep up with any of them because my heart was so distracting. I really was quite concerned and my poor heart is still struggling and pounding very hard.

So, here's the kicker - with the last energy drink I also took 200mg of Wellbutrin.

So, my question is :

- Can you overdose from energy drinks? And if so, what are you overdosing "on"?

- Could the combination of Rockstar and Wellbutrin be some catalyst to disaster I didn't know about?

Thank you all for your help.

Rockstar has a high content of Guarana and it is not know in medical journals to produce overdose effects. However on occassion people may be allergic to certain ingredients, and this may be what has happened.

If you are concerened about the safety of energy drinks there is a government publication on the issue http://www.safefoodonline.com/safefood/a...
