@LucyDee I took mersyndol as a teenager for severe headaches and only stopped in my thirties when it stopped working as well. Then when I started getting migraines in my forties (once a year) I started taking them again for the three day recovery process. I also found they were the only thing that helped with period cramps. They are not currently in my house as I do not want my body to stop responding to them if I need them again. However, when I had BC, I made an exception.
