I have to admit, I'm an energy drink junky. I used to not be able to drink them they made me jittery as fuck.. now I'm at one or two a day (years later). Not sure where I made the transition, I think it was in college... I've quit a few times, go months without them, after getting over the massive headaches you get from abruptly stopping the caffeine intake I find that I have more energy without them. They don't really taste good- especially the potent ones. Yet I always find my way back to the habit within a few months.
