I had been an intermittant migraine girl forever--after a fall and concussion I had constant headaches. The doc put me on a low dose of amitriptyline (so low, she called it 'tincture of nothing') and it has cut down on ALL my headaches, to the point where I have headaches like a normal person--you know, those people who notice that their head hurts, and then they can take tylenol and feel better.
