Chelation is a process by which toxic substances, like mercury, can
be removed more rapidly from the body. It usually involves taking
various drugs and/or supplements. Why did you have your amalgam
fillings replaced? Was there a suspicion they were causing health
problems?

I have certain visual migraine triggers too. Usually they involve
trying to focus / concentrate on moving objects. A few seconds can
be all it takes to trigger 3 weeks of migraine associated vertigo.

Do you find if you do less travel and fewer visual tasks that your
dizziness lessens? It works for me, but sitting still doing nothing
gets old real fast.

Previously, you had mentioned food items. I’ve not found any that
make my migraines worse. In fact, sometimes chocolate seems to
make the symptoms lessen a bit. Might be just an effect of caffiene.

The drug that worked wonders for me was prednisolone. At about a
15 to 20 mg dose per day, I felt sooo much better. The doctor thought
that too high a dose to take routinely, so I’m stuck now probing
for another solution.

As thyroid hormone, have you ever tried Cytomel (T3)? I was getting
very achey leg muscles until I added some of it to the Synthroid I
take.
