I had a thing for Red Bull and Mother for a while before I realised that the only reason I was drinking it is for the short energy hit while ignoring the shitty taste. I stick to classic Coke now, it tastes good and that's all I want from a beverage.
I'll have the odd energy drink every now and then, I'm quite partial to a lemon ice Relentless and Red Bull. Most of my energy comes from tea and I also find that the morning cigarette gets me up a bit.
Frequenting audiophile forums for so long made me think that you were listening to some music on an amp that draws 3 amps of current, and thus would be quite powerful ;-)
As for my favourite energy drinks, I always buy the LIDL quite unoriginally named "Mixxed Up Energy Drink" line with some OMF-like dancers. They are about 1/3rd of the price of Red Bull, and the ingredients are exactly the same. Most of those drinks also taste exactly the same (like cough syrup).
In the past they also had "Freeway Energy Dring" with a tiger logo, and a "Sitting Bull" energy drink (maybe it gives you super-sitting energy?).
Here's the complete LIDL energy drink lineup. Some of those I'm familiar with, others not so much.
Too bad they're virtually nowhere these days. (besides the internet)
Damn, I remember when they used to have those at college. I missed that so much once it disappeared from the shelves.
I still have the occasional red bull or monster energy drink, but mostly I stick to good coffee/espresso. I'll also buy a Starbucks Double-Shot in a can for days when I need a good extra few hours of energy
The only* flavour of energy drink I enjoyed on its own was Full Throttle Blue Demon. After those disappeared off the shelves, I only grab whatever catches my eye on rare occasions where I desperately need to stay awake. Other than that, I buy cheap $1 cans of Rip-It or Red Rain to make Jagbombs with.
EDIT: Actually there's a Sonic the Hedgehog energy drink that I tried once that was better than that.
They sell Bawls at Costco. :) Loves me some Bawls.
Anyway, I sort of bounce around between drinks. I always drink coffee, but right now I'm drinking a lot of sugar-free Rockstar as well. I also like sugar-free Red Bull and diet Coke, but haven't had them in a while.
