Coffee is one of the most widely consumed beverages in the world. It is prepared from the roasted seeds—commonly referred to as beans—of the coffee plant, and is usually served hot but can also be served cold. A typical 7 fluid ounce (ca. 207 mL) cup of coffee contains 80-140 milligrams of caffeine, depending on the method of preparation. Coffee represents 71% of all the United States caffeine consumption followed by soft drinks and tea. Coffee, along with tea and water, is one of the most frequently-drunk beverages, its volume amounting to about a third that of tap water in North America and Europe. In 2003, coffee was the world's sixth largest agricultural export in terms of value, behind wheat, maize, soybeans, palm oil and sugar.
And I LOVE IT!!! Especially since I started working, since I start @ 7:00 am, The coffee at work is free so I usually try to be at work 6:30 - 6:45 so I can sit and talk with my coworkers about the stuppidest things, drink coffee and start the day nice and easy!! And then at 9:30 I drink another cup of coffee, at 12:00 usually 2 cups of coffee, and then at 14:30 my last cup of the day.
Since I drink my coffee out of 150-200ml plastic cups, thats about 160ml coffee a cup average
160 * 5 = 800ml coffee a DAY
800ml * average caffein in coffee (about 110 mg/200ml ) = 440mg caffein a day... AND I'M STILL TIRED.... maybe I should go to bed earlier :) or drink even more coffee... hmm, I think I'll go for the more sleep part
