I also used BW tincture for parasites and candida (non-alcoholic and alcoholic) and got hyper feeling / wired and jittery after HALF dropper.
I would pee myself in a minute after that BUT nonetheless i felt it gave hard time to the small bugs.
My guess for my case was related to Iodine content of that tincture that gave my low thyroid a super boost. And force also my adrenals in cascade. Also too much too soon can create more inflammation thats true.
