How do I get more energy?

I take B12 (It's an energy increasing vitamin) that you can buy anywhere vitamins are sold. I don't drink energy drinks like Red Bull or Monster because they are bad for you and are loaded with sugar which will end with a crash. However, 5 Hour Energy Shots REALLY work and have no added sugar and are good for you, not bad, plus they are small and don't make you feel bloated. My neurologist recommended I drink coffee because it actually helps you focus at school really well and isn't BAD for you in moderation. Good Luck!
