I bought some and they honestly seem like more trouble than they are worth. You must take 4 tablets dissolved under the tongue every four hours. They got really great reviews on Amazon when it came to pain management, but I haven’t noticed that they work at all. Still have to take paracetamol for headaches / inflammatory pain. My nurse told me not to bother with any products that are over-hyped on the Internet without any clinical backing, but I thought I’d give these a try since it wouldn’t do any harm. Probably wouldn’t have done it again.
