I've been doing 2 20 minute sessions everyday with small amount of baking soda included in the aluminum tray with no results yet. It has been about 3-4 days
I've had results in a few days, but that may be atypical for most. I'm not sure what everyone else is doing, but I would think that session length, amount of voltage, and conductivity of the water bath play a big part in the effectiveness of Ionto.
I'm defining a session as the time I start applying current to my body, plus switching polarity, and running until I am no longer applying current to my body.
So what I do is run my Ionto on one polarity for 15 to 30 minutes, then switch polarity and then do it for another 15 to 30 minutes. In this respect, my treatment (or session) will range anywhere from 30 minutes to 1 hour.
The voltage will be between 14-19. The current is roughly 1.5 milli amps.
I've increased the amount of baking soda and salt in my water bath and feel I get better results. My measurements aren't exact, but I would say I use a combined measurement of about 1/4 to 1/2 cup of baking soda and salt per 4 cups of water. The itchy/stinging feeling can get pretty uncomfortable after I reverse the polarity. That's always the worst part, but being able to control the HH is much more important to me than feeling uncomfortable for my 30 to 60 minute session.
