I'd just cut out all the sugar from my diet if I was you. Get your energy from real food and up your water intake to where you're barely drinking anything else all day except for your morning coffee.

I'm a self employed truck driver and when I'm working, I put in hours that most people would not believe. The most often asked question about my job is..."how do you stay awake?" The answer is: getting enough sleep, not eating crap and drinking lots of water. I see drivers and tourists on road trips loading up on 5 Hour Energy, Mountain Dew, candy and chips.

They'd get more out of a couple pre packaged boiled eggs and water.
