First try out the instruction from the idromed 5.
Then you have to experiment.I use Idrostar,followed the instruction.But after a little experiment I found out that for me it was best to do ionto everyother day,,,think I took 14-15 treatments...then I take 1 time a week and stick whit that no matter what.I also slowed down the power from 20-22 mA to 10-13 mA.
Think that overdoing it can be wrong to.
I also use dehydral cream only for my fingertips 2-3 times a week before bedtime.
For example the instruction for Idrostar device is like this.
First week -treatmeant on day 1,day 2,day 4.
Second week -treatment Day 7&day 10
Third week -treatmeant on day 15
Fourth week -treatment on day 22.
10 minuts on eahs polarity,then switch polarity.( 20 min together.one hand/one foot)
Then shift, same process.
Hope this helps a little...If this is not working even after experiense, I would try to find out if the ph in the water is rigth ,,hard or soft enough etc.I dont know the right Ph then,but the water where I come from works for me.
