Pepsi cans and bottles will soon disclose the exact amount of caffeine in each serving of their colas.  Other makers of caffeine containing products, such as Coca-Cola and coffee companies, should follow suit. 

It is interesting to note that there are significant differences in the caffeine content of such drinks.  Per 8 oz serving; Pepsi has 25 milligrams of caffeine, Diet Pepsi has 24 mg, Pepsi One and Mountain Dew have about 36 mg, and a 16 oz cup of Starbucks coffee packs 260 mg of caffeine.

With the increasing line-up of caffeine containing foods and beverages on the market this information will allow us to tally up our total daily caffeine intake and avoid stimulant overload and addiction.
