Ouch! I don't know it's a change in blood flow or dehydration or what, but I get annoying headaches every single day!! All over -- sometimes sinus, sometimes tension headaches along the back of my head, OWW! And Tylenol (a) won't touch them and (b) can't be great for my liver on a daily basis. Any tips/tricks? OWWWWWWWWWWWW
