Energy Drinks? Who needs them?

Truth be told I am the only person in my office building that drinks Diet Dr. Pepper. I tried Tea, not strong enough. I tried energy drinks, too strong. I get too shaky. My hands start to tremble. Which made me think? Are Energy Drink just another marketing success story. Like plastic Water Bottles for a $1.00. These Energy drinks often cost between $1.75 to $3.00. Are they really worth it when you can get a Diet Dr. Pepper or a Diet Coke for 0.75 cents?

I don't like them at all I am sticking to Diet Dr. Pepper, even if people think I am wierd.
