Thank you very much to Jeffrey and Joe for the answers.
I am looking for the information I need right now.
You are always welcome to my country where I live in the south of the Andes, the mountains in the border to Chile, in a city called Bariloche. I enjoyed Dr. Zeig's conference here some years ago when I discovered Erickson's world. I am a dentist and I often use Ericksonian techniques but dont tell the patientes...they just relaxed and most of them snore!
Sorry about my english I am still studying to improve it.
Kinds regards to all of you and keep in touch. CLAUDIA.
