Drink the most highly caffeinated beverage you can find, although i dont drink them myself (cause they are pretty bad for you) the energy drink 'Nos' seems to do the trick, (warning: they actually have an age limit as to how old you should be when drinking it, and please... Dont drink more than one, its way bad for you but itll keep you going) For me personnaly, i do Pepsi and cheese its, and sometime a glass of ice water
