thanks so much for the details. I am sorry to hear that your health continues to be a problem after so much work. Perhaps this is a difficult parasite issue. Curious as to whether or not you have tried long fasts. I think if all else fails its a good last resort (maybe along with prayer..)
Mark 9:29
He said to them, "This kind can come out by nothing, except by prayer and fasting."
I hope you find the solution soon, I know its hard to keep working on ones health (for me 3 1/2 years) God Bless you.
