Hi again. I also take 6000 mg's of disolvable iron under the tongue. It does not help me. But still, perhaps You should have a complete blood panel test. It could not hurt and usually reveals so much of what is going on within the body. Also, I have just started going to a new oncologist who will start treating me in the manner that should have been treated. Now we will be more hopeful. Good luck, Peach.
