If you really, REALLY have to have energy right this minute, go to your local GNC and pick up a four-pack of Redline. It’s a few steps above your everyday energy drink.
SoBe NoFear, Sugar Free.
I CRAVE that stuff. I just went through 9 cans of it in 9 days (that’s all they had left at the store) and I fear I may have bought the last of it in 4 cities 
My current poison is Full Throttle “Mother”.
I’ll sometimes go through a whole 4 pack of Red Bull at work, on the days that I drag. The habit’s getting to be a drain on the wallet, though, so I think I’m going back to the REAL original energy drink…Black Coffee.
I will admit to being a Red Bull fan. It tastes great and does pretty good at the energy thing. I used to love Monster drinks when I worked at a carryout, I would drink them almost all the time. The different flavors are all good, and recently I tried the Monster coffee, which isn’t bad.
Enviga is great. I wrote my senior seminar paper (all 30 pages) while drinking about 6 of the berry flavor. Also, for the health-concious, try Sobe Adrenaline Rush in the blue can. I bought both orange and blue, looking for two flavors. Instead I got a sugar free that I love and a regular that is tolerable. Sugar free has only 10 calories.

Not when you’re drinking it for the caffeine, smartypants. 
Heh. I was at a Pilot truck stop last week, and saw these little beauties, to add to your REAL original energy drink. The advertising read “Put more coffee in your coffee”. I haven’t had the nerve to try it yet, but next time I see one, I think I will! It was “free”, too (you still have to pay for the coffee, but the Stok was right there with the flavored creamers and stuff you can add to your coffee at no additional cost). This would make a really cost-effective way to consume a serious quantity of caffeine in a fairly short time!
Where the heck do you find this? I’ve looked for it everywhere, and it just doesn’t seem to exist. Isn’t this the one that Coke started off saying it had negative ten calories?
