I took 20 mg a day for four days, and during those four days (and for several days after) I experienced lightheadedness/feeling faint, headache, nausea, loss of appetite, akathesia, irregular/rapid heart beat,
racing thoughts, EXTREME anxiety, insomnia, and flu like symtoms. All of these were so debilitating, it was difficult for me to even get up and walk around. Naturally, I stopped taking the medication.
