|plusaf's Caffeine Project rev. 11.15.2008||Back to Lessons|
It started for me around 1972, when I started having really bad headaches, always just above my right eye, every Saturday afternoon!
What was the difference between all of the other days and Saturday? On Saturday, I didn't drink coffee.
Monday through Friday, I'd had, on average, up to 5 to 7 cups a day!
Suddenly, my body reacted to the caffeine. I'd pushed my body over some limit.
If the person answers, "yes!" to these questions, they're a caffeine addict, and they can often cure the headache within an hour or less by having a cup of coffee (real, of course, not decaf!) or a can of non-caffeine-free cola!
I need your help. Well, a very special "you": I'd like to enlist the aid of someone with access to special equipment (probably a chemistry lab with a gas chromatograph) to do some research for me. I'll publish the results right here, and if you want credit for the work, I'll put your name here, too.
What I want to find out is, how much caffeine is there, really in a variety of beverages, some of which may even claim to be "caffeine-free". I have a suspicion that, in some cases, "zero" isn't exactly equal to "nothing"!
