I have been using the Fischer md 1a for about 6 months now. When I began, I had beautiful results. However, my hands started sweating profusely again for seemingly no reason. I use as little water as possible, did not change my voltage, and did not change my water. I’m currently taking a break from iontophoresis in hopes that it will work when I resume. Any thoughts or helpful hints for me? My palmar HH causes me a lot of social anxiety and frustration.
