If you still need more options, I'll take it. I require caffeine to care for people at 3 in the morning 
I did at one time buy Duncan Donuts ice coffee with extra, extra before work. Kind of made me feel guilty as I could make that at home and every penny counted.
I noticed that after drinking a large I had to run to the bathroom to pee more often and when I peed my sugar level fell so low I was groggy. Sort of like the feeling after eating Thanks giving dinner one want to fall asleep.
Never tried Starbucks, the idea of paying over a dollar for coffee was crazy. Coffee is just flavored water and I remember buying a cup of coffee for 25 cents, sugar and cream free.
Worse coffee I ever had was at a rest stop on the NJ Turnpike. A large that came black so I grabbed some cream packets and sugar and got on the road again. The cream had soured and was crap. I there after learned to drink coffee black, just colored water.
I am sure Lot's of you have had some interesting experiences buying some kind of coffee at some time in your life.
Then the question, does the caffeine in coffee do more for a kick booster then a 8 ounce glass of orange juice ?????
Have we been sold a bill of goods from the coffee industry that Caffeine will boost ones metabolism over fruit juice ?
Then the Tea industry, interesting history, wars were fought over tea. Part of the spice wars that raged world wide.
