I started taking Robinul last year for my sweating hands and feet and scalp, my head would sweat profusely every time I went shopping, had any kind of deadlines to meet, etc. It started working within 2 days. Not a cure, but not nearly as invasive or dangerous as other solutions that aren’t guaranteed to work. However, it is very expensive and also I seem to be gaining weight around my middle quite quickly and it is also showing on the scale. That is the only side effect I experienced. I wonder if anyone else had any weight gain when taking this drug?
