Sodas and caffeine

[ShakeZula06]

How bad for you is it? Is there anyone here that works out a lot and drinks caffinated soda? A lot of times in the morning on the way to work or school when I've gotten <8 hours of sleep I'll grab a soda at QT and that will be my breakfeast. I know it's horrible but it get's me through the day and costs me minimal time.

I'm 19 and never really been concerned about health until recently. I have a real high metabolism so while I eat more then the average guy I'm pretty skinny (5'9, maybe 150-160) and want to start changing my eating/drinking habits.
