Please please don't drink energy drinks they're terrible for you. I started drinking them daily in year 7 and by year 11 I was drinking around 2 litres, sometimes more, a day and it ruined me. If I couldn't afford many energy drinks I would get withdrawal headaches which were debilitating. Took me about 6 months to finally get off them. Energy drinks eventually had no effect on me and didn't wake me up, just made me feel "normal" because I was addicted.
