And how does that help your argument
It only means that the one pill of guarana you took has even less caffeine than I assumed it had, meaning that the effect you got from it was probably a placebo unless you also get this effect from very small amounts of coffee.

I don't drink coffee that often, as I get caffeine headaches, yrs back, I found a way to cure this by drinking yerba mate, when I started getting caffeine headaches, as it was less of jolt than coffee. But depending on the strength of the brewed coffee, I'd say all things being equal, meaning the same amount of each being brewed, wouldn't the drink made from guarana have more caffeine, as it contains more from the beginning?
I picked up the supp yesterday, on the back it says: Guarana seed extract-----250mg
(Paullinia cupana)(36% Caffeine=90mg)
