Why are my hands shaking?

Ah.. theres no better sound than when you pop open a can of a cold energy drink. You can hear the fizz and know that in about 2 seconds, your body will be pulsing with energy. Just thinking about it is making my leg shake up and down anxiously. One small problem with me though; They don't work. Coffee, monster, rockstar, amp, red bull... they don't kick in until about 3 hours later. And by then, there's no reason for me needing extra energy because I've already crossed over into deleriousness. Ah ha! Another word I've made up and added to my own personal dictionary. Anyways, yeah. Energy drinks don't work on me. But that still doesn't stop me from buying them. I have a problem with money. I seem to have an extreeeemly hard time saving it. Sure, I put a lot of it into the bank, but I spend a lot too. Probably more than I should. My excuse for it though is that in these bad economic times, I need to do my part in helping stimulate the financial.. issues. Haha, well at least that's what I tell my mum.
