Your symptoms are purely psychogenic. Finasteride has been perscribed for over a decade in 5X the dose you are taking. There is nothing in the literature about "spacy" or increased aggression or any of the wacky symptoms you have.
DO you have a history of psychiatric illness? Have you seen a psychologist or other mental health professional for treatment?? Your answers lie here. Certainly not in a 1mg pill of finasteride.
Tom, man you are wrong. I have no probs man and since being on finasteride i've had more of a temper, i feel a bit foggy, and im not as enthousiastic or happy as i usually am. Its like im semi depressed for no reason or something. Will dutasteride have the same effects?
