A welcome from me as well Peter. It is really great that your treatment is working however I would suggest looking up Brian's expert contact in Stuttgart.
Your English is perfectly OK and while my spoken German is fluent and reading is not too bad, writing is impossible as I was educated in English.
There is so much information here that will be of help and of course plenty of people who can answer your questions.
