Danielle,
you certainly are an exception to the rule. Here in Greece people who start on exjade, turn to leave it in the end because their heart and liver T2* rates drop after a while - I, of course, am talking about exjade as monotherapy. It is, nevertheless, a solution when your ferritin does not come down inspite of your compliance with chelation when on desferal. But when your ferritin drops with a combination therapy, then you should stick to that. That is only my personal opinion, of course.
