Thanks, J. Those sites were helpful.

We have what we need; I was just wondering if someone else had experience
with this treatment.
We had a "parts problem," since there are several "systems" one can use, and
they all have to fit/work together,
the hosptial gave us one set, and the pharmacy had another. So we had a big
run-around. But everything is fine, now.

Since entering this medical world, we have had to change our mindset.
Instead of trusting the good doctor, and going home all satisifed, we now
document, record, ask, anticipate, check out, verify, re-affirm and research
just about everything.
It is not that we don't trust the good doctor - we do. But we have learned
that this is a business, with lots of people and lots of patients, and even
though good people are helping us, we have to be on top of things, because
reports get lost, people forget, communication lines break down, and then we
are left at the mercy of someone else picking up the pieces.

I guess in a long-winded way, I am saying that one must take charge of their
own treatment, in as many ways as possible.
So I was fishing for some roadblocks or problems we may anticipate that
others may have experienced themselves.

Thanks for your help.
