what do you use to keep you going?

Yeah... and when neither red bull will do the trick you could try some toothpicks... tom & jerry style... I use air breaths, water with some lemon :P, peoples smile, and some priority stuff... good luck

Coffee coffee and more coffee. I got news for you I drink about three pots of coffee a day I don't sleep much but that is alright I never slept that much to begin with.

I would have some coffee or tea and have some biscuits.

For me it's tea (green & black) and energy drinks (monster, rockstar). Energy drinks have the caffeine content equivalent to that of a cup of coffee; however, they usually have about 2 grams of taurine (the word taurine comes from taurus, meaning "bull" in Latin, hence Red Bull's name), which is where the energy comes from. Energy drinks don't have the low depressing after effect that caffeine has, but they usually only sustain me for 3 hours. Personally, I don't like the taste of red bell; I think you should try monster or rockstar juiced instead.
