Before I used to sweat the most in my back, then buttocks, then belly. Then I started taking Glycopyrrolate orally and it works good.
However, it blurs the mind for about an hour, and afterwards I enjoy the sweat reduction effect with a bit of dry throat and casual headaches.
The way Glycopyrrolate works for me is that it reduces the heavily sweating areas first, making the sweat more balanced and reduced. I also suffer from feet hyperhidrosis and didn’t have ETS for it. Glycopyrrolate doesn’t work for me in that regard for some reason, even if I apply it on the feet.
