you were drinking 3-4 of them a night DUH!!! of course you were having heart palpitations. There is garbage in that video. I have 1 16 oz a day....... now I'm not claiming im fine but at the same time never had any issuesIts truth to alot of what the video says. I used to drink Monster Energy drinks daily, plus Red Bull while working in bars/clubs as a bouncer where I had free access to Red Bulls so I would even drink 3-4 a night. The drinks made me hyper, have heart palpitations and irritable where my moods were synonymous to roid rage. I don't fukk with them or 4 Loko anymore as per docs orders.
