Jesus Christ I'm sorry for what is happening to you.
I think if you are against chemo and everything from the medical community, at least begin the LugolsIodine again.
For the phlegm I hear that Acetylcysteine is good for that. I have used it and it helped, it actually is used for cystic fibrosis which causes a lot of thick mucus.
Here is a link from Wikipedia that explains it further and good luck and God bless.
Acetylcysteine, also known as N-acetylcysteine or N-acetyl-L-cysteine (NAC), is a medication used to treat paracetamol (acetaminophen) overdose and to loosen thick mucus such as in cystic fibrosis or chronic obstructive pulmonary disease. It is available by intravenous, by mouth, or inhaled as a mist.
