5 Stars with reservations
It takes a month for this to take effect ( according to research I have done).  I have been taking it that long and my headaches are less frequent and less severe when I do have them.  That said, I have also started some diet changes at the same time I started taking these and with THAT I saw immediate results.  So I can't really say how much is the Petadolex or the diet?  I don't notice ANY bad effects, so I will give these pills some of the credit.  guess I will have to stop taking them, keep up the diet changes, and see what happens?
