it sounds like it only helped the headache so much, because it was caused in the first place by the withdrawal of the caffeine.. so it's not a headache cure, but replacing the drug that was being withdrawn from.
would that not have been caffeine withdrawal though ? If you'continued with the de-caf, those symptoms should've gone in time, like any drug you're gonna notice when you stop taking it.
