I'd be curious for the offical answer as well. I seem to recall reading part of a European journal article on PubMed the other week that said only 30% of patients ever see a total or partial remission, but I am sure I am off on that. Personally in 25 years, I've only had 4 years intermixed that was relatively symptom free.
