Thank you to all for replying: i'm still reading and more i read and more i think all it's very difficult. Now i'm trying to have a deeper understanding of the scale of sensitivity.

To GM: yes,i was referring to your method, but also to others i sow during this years.
Could you please give me an advice about a source for reading more on D potency?

By myself i use only 5 or 6 c, and i think it's more than enough, but i had some situations where it didn't work: with the advice of my homeopath i used higher potency of the same remedy, that didn't give any effect in lower potency. How could i understand that the potency was too low...if it was for me i would have changed the remedy (i'm referring to an acute episode).

To Ben Rozendal: sorry, but i couldn't understand what you want to mean with "less wasteful"...less dangerous? Are the Korsakoff potency lower? Would you compare them with LM or are they closer to C potencies?

To all: any book to suggest on this subjects? It is very tiring to read on the net.

Again: thank you for teaching me
