I just quit drinking energy drinks (again) two days ago. I always got low carb or sugar free ones though. Really don't like the taste of sugary drinks. The Zero Carb Rockstar (in the blue can) was always solid. Big fan of the Monster Rehab Lemonade/Tea, but it always goes down too easy since there's no carbonation (usually wound up drinking two of them).
But the granddaddy of all energy drinks is Cherry-Lime Xyience and it's not even close. It tastes friggin amazing, too good in fact. I used to kill those babies on the regular. There used to be one gas station in the county that sold that flavor, but they stopped selling it late last year. Pretty sure it was a personal attack against me. Not sure if I arrested the pizza boy somewhere along the line or what the hell happened. But I can't get it anywhere while I'm on duty unless I wind up on a prisoner transport or something like that where I can get out of the county. I've been seen in uniform completely cleaning out the shelves of some convenience stores from time to time.
In fact, I was on my way to training in Minneapolis a few days ago and had every intention of cleaning out the shelves at a Holiday Station where they always sold them 2/$4. But they jacked the price to like $2.59 a can. I was pissed, so I walked out without buying a singe one. I've gone a couple days without an energy drink now, and I figure I'll stick with it. The headaches didn't start kicking in until about the third day last time. So they'll be hitting me hard when I get back on night shifts tomorrow. Good times, good times.
