I have palmar and plantar HH. I've been using a homemade iontaphoresis solution for awhile now and it seems to work for the most part in controlling the sweating in normal situations, although I would love it to stop when I exercise, but that might be wishing for too much. In any case, have others out there experimented with the duration and frequency of their treatments? In other words, have you found that doing longer treatments and/or more frequent treatments make a difference in how quickly your sweating stops?
