I want to like this product but the package has no description of the product, there is no instructions to use either. I wonder if the patches to be applied to both feet, why there are 5 in the package? I'd think they need to come in even numbers. Since there is no description, I have no idea what to expect, thus I don't know whether they work or not. The pads do stick well and stay put on all night. however what is this gooeye stuff?
