BW, I had no real success on my own. Just trying things and not knowing good doses and brands. At first, I had a integrative doc. in Cal. Years ago. He is the first doctor to know ANYTHING about CFS, I had seen many. He gave me great blood tests. My B-12 level was AWFUL I then saw a nutritionist that is a PHD in Fibro and CFS. SO SMART!!!! He was my hero! He worked with a doctor and I got B12 injections and my life changed. Vertigo slowly stopped. I felt better, I was bedridden with vertigo for a while. I took other things with him. I had to move away just two years later. It was so hard. Took several years to find a new doctor.
I work with two integrative doctors now. Dr. Dzugan (you can google him) works with my doctor. My CFS doctor had great results working with him for patients so she told me I could try. She had been helping me with CFS for several years, but then POTS hit. I was too sick to see her, four hours away. NO doctors near me knew what was wrong. I live in a very large city known for it's doctors... I soon got good enough to go see my CFS doc. Then she was able to help my POTS. NIGHTMARE. That is my main problem now. I have supplements helping THAT too!
Anyway, yes, I have two MD's. Integrative doctors. VERY knowledgable about supplements. Good blood tests every four months or so. We are watching my vit. D go up, Epstein Barr go down and hormones are balanced at LAST.
I just started Choline. It is good for me too. I really have no fog at all. You do need to find good help for supplements. I cannot tell anyone what and how much to use. We are all different with different needs. I needed CoQ10 badly. Some people do not. I had multiple things I needed and I think a lot of people are like that. Not just one or two things.
