And if you're someone like me - beware that 'decaf' really isn't. Even as little as *5 mg* of caffeine causes me everything from sleeplessness to migraines (verified with a double blind study administered by my wife!)

(1) Experimenter dissolved measured weight caffeine powder in water, and divided it into various measured portions, and labeled them with unique numbers. Then made identical measured portions of pure water, also labeled. She sealed the number assignments in an envelope.
(2) On experiment days, I chose a water portion, recording the day and number in secret - she could not see which portion I chose or what number it was. I then poured the water into whatever (zero caffeine!) drink (or whatever else I could mix it in with) I was having. I used drinks and food with strong enough flavors that I definitely could not taste the possible caffeine addition.
So now neither of us knows whether I took one of the caffeine ones.
(3) I recorded the day's results.
Decaf coffee tastes about the same as regular coffee (some people claim to tell the difference, but I can’t except that when I get decaf it’s the cheap mass produced stuff and for regular coffee I like to support local roasters). Maybe the taste was triggering the same effects?
