You might be getting more caffeine than you think

Someone tried to tell me the other day that the tea I was drinking had more caffeine than coffee. I dismissed this statement because although I know regular tea has quite a bit of caffeine, it doesn't cause nearly as much of those nervous jitters that too much java leads to. But I decided to look in to it, and this is what I found -- Black tea has about half the caffeine of brewed coffee, and green tea has even less than that. Also: some soft drinks that you wouldn't think have caffeine do, including Mountain Dew, Cream Soda, Mellow Yellow and Sunkist Orange. So if you're watching your caffeine, cutting out the coffee might not be enough.

Another thing the article points out? A Grande-sized coffee at Starbucks has twice the caffeine of a regular-sized portion of coffee, so don't fool yourself into thinking that one cup actually counts as one.
