@maxwell123 Thank you so much!
Yes, his normal doc is on vacation for the week, and the doctor covering for him seems to want to be fairly aggressive about the dialysis, and made some inappropriate comments about why, in front of my husband to the nurses (The nurses asked why the change, what he was basing this change on, and the doctors response was "I dont know, I'm just guessing"). He hasn't had any side effects for a while, and yesterday was the first time since the 2nd treatment.
So far, despite his love for red meat, he is very open to the plant based/low sodium diet and it seems to be doing well in the short amount of time he's been doing it. I've done tons of research on the herbs, and they seem to support their usefulness. Also after speaking with a pharmacist about them, the Pharm.said that it would definitely not hurt to give it a try. I wanted to make sure of all this prior to trying anything with him as the situation is so intensely serious.
