fioricet, but does not seem to work, or if it does work, it is for a very short time. Now the doctor prescribed fiorinal because fioricet did not work as well and because it seems tylenol is quite dangerous. Does anyone know is it the codeine that was so effective on my headaches? I believe they are either sinus/allergy, tension or stress headaches. Though when I have a headache i am very sensitive to light and sounds, i dont believe they are migranes, but i do get them very often, several per week, sometimes daily. Thanks all.
