Bill - the rust image caught my attention too.  I had severe anemia
about 4 years ago and have been taking iron every day since.  I have
heard that it is not a great thing to do with Sinemet and Permax and
Eldepryl.  But is it a bad thing to do?  and what is the impact?  No
doctor has ever told me to stop, but I think I could because my
hemoglobin is way up there in the very good range now.
