I have to leave for work at 4 AM three-four days a week.  Sometimes I'm so tired I can barely keep my eyes open.  Well, lately I stumbled upon the world of energy drinks.  I found that Monster Low-Carbs have only 20 calories, 6g carbs, and 6g sugar in a whole can.  However, they have 2500 mg of "energy blend" that includes caffeine and stuff.  The problem is, I LOVE the way these things taste and they give me a perfect dose of "kick."  
So, I guess nutritionally this stuff isn't too bad. However, I'm concerned about the caffeine. I would say I drink three-four of these per week. Is that too much? What are some adverse effects of these energy drinks?
Thanks for the help.
