Caffeinated Drinks Are Toxic & Awesome.

I've been feeling so tired these days. I don't sleep that late anymore though. Well, I have a stash of the original & purple AMP energy drinks & it seems to be the only thing that keeps me goin. I just found out that the purple grape flavored AMP SUCKS! It tastes ohkay, but the caffeine in it didn't have much effect on me. Cause today, I had one can & throughout the day, I still felt a bit tired & my eyes wanted to shut so badly...I'm never buying that purple one again, lol. Original,which is the color green, is so much better & keeps me wide awake. I read that energy drinks have at least 10x the amount of the caffeine that's in a cup of coffee. They say it'll give bad side effects on the long run or even cancer. Ohkay, the cancer part, I don't know if I can believe since it's never scientifically proven but then anything could happen. Honestly, I still like to drink it. I just don't drink it daily or anything cause I don't need that much caffeine or a boost. I only drink it on days where I know I'll feel really tired. There isn't really an alternative drink for me except for Espresso, which I also love, lol. But yeah, it shouldn't be too harmful if I'm not drinking it like every week. I drink it 3-4 times a month...Due to budget reasons, haha.
