I used to drink energy drinks all the time. I havent had any in awhile (I gave up all carbonated beverages and such for my running a few years ago), but I used to do two of them alot, one was called Magic, the frist time I tried it was when a guy was passing out free cases at a Michigan football game when it first came out, me and my friend each got one, then later we saw him and he was about to leave and didnt want to take the rest with him, so I ended up with like 8 cases, I drank em a ton, and actually after I ran out I found them at target and bought a few more, target was the only place I ever saw them, and I’m not even sure they still make em, but I loved those. Also, I did one a few times that was called A Can of Whoop @$$ (or something like that), that wasnt bad either. I find that I do much much better with just water these days though, and the occasional gatorade. When I used to drink all the energy drinks I would get very jittery, then I got used to it more, and all it did was give me horrible cramps all day.
