I looked up the archives of the french list and found one msge, 4 year old, of someone ( a MD) who had it for 18 months. His wife ( a nurse) managed it. He said had good results with it but had to stop because of cognitive troubles. He said you have to be very precise with the doses. sorry, nothing more recent maryse ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
