Well, some of the people here wrote that they did use it, and Robert said it worked for him in his hyperhidrosis story, but I am not sure what do you mean by “off line”? Is that like an “off-label” medicine? Or one you can get without a prescription?
Whatever oral medication you use for treating excessive sweating, you’d do best to be careful and consult your doctor first. You always must be careful about the side-effects. Better to sweat too much than acquire some worse health problem!
I hope you found what you were looking for, though. Everyone deserves to find a hyperhidrosis cure! 😉
