I had sever neck pain which I never had before (I am 78) I took one pill in the morning and it relieved the pain and stiffness in my neck. Then I took one at night. The heavy pain and stiffness didn't returned. Next morning I was questioning the dosage which I am searching for now. I am happy but I would be happier if I know more about this drug.
