All i take, due to my paranoia about drugs in general (thanks, adverse reactions of the past!)
is Panadol, which
is paracetamol, similar I think to
your Tylenol? But I have to take it daily lately too. I was just today at my dr and asked if I might be getting rebound headaches from taking too much, but due to other things going on and my age and gender, he was more inclined to think it was menopause-related. GUess that's off your list though!
