Hey, I completely sympathize with you on this one. I have struggled with severe hyperhydrosis in my hands feet and armpits up until last year where I finally figured out the combination that works for me.

Hands and feet - Iontophoresis. I saw you said in a post saying that you tried it and it did not work but it does work with dedication. I thought the same thing at first because I tried it once or twice and still sweated. The key is to do 30 minute treatments of it daily until your sweating reduces to where you want it. For me this is about 2 -3 weeks of daily treatments until my hands and feet stop sweating completely. After that I do 3 30 minute treatments weekly to maintain it.

Armpits-I use Odaban Antiperspirant which is a strong otc antiperspirant. Every night I apply it to my armpits before I go to bed and it works. Just like iontophoresis the treatment will take a few days-week to work completely. It is also very important that you apply it before you sleep.

They key is dedication to the treatments. If I let up on my maintenance it does come back quickly. And you will not see results in the first few days or week at all.

I hope this helps!
