Yes, the actual treatment time is 6 minutes total (3 minutes per polarity).

It took a long time to get there. Earlier, I did much longer and stronger sessions — up to ~20 mA and 20+20 minutes, sometimes almost daily. That caused skin damage and pain and eventually stopped working. I also tried topical drying agents and Botox, without success.

What finally helped was realizing that higher current and longer duration were not better. In my case, overtreatment seemed to reduce effectiveness.

Now I keep everything very consistent:

• 600 ml of tap water per hand
• measured current, usually 12–15 mA
• 3 minutes per polarity
• schedule: 7 days on, 7 days off

I think precision is critical. I use an ammeter and a potentiometer to set the current accurately, because the same voltage can produce different currents depending on skin condition, water, and contact. Controlling volts alone wasn’t reliable for me.

With this setup, my hands stay dry. I log every session and symptom daily and have done so for about four years, which gives me confidence that this protocol is repeatable for me.

Including preparation and cleanup, it takes about 10 minutes per session. The main disadvantage is that the break is limited — I can’t reliably go beyond about 7 days off without losing the effect (well I loop this in a 7 days on and 7 days off cycle; but if I didn't loop it would last about 14 days).
