Hi Nabo,
do you really think it's IRIS ? If you have much pain, I would think that whatever virus is causing your illness, is replicating. Have you ever tried selenium ? The reason I suggest replicating virus is this:
I started a while ago selenium to treat my Thyroid, which worked very well. Note, I'm on Gc-Maf too. After a while I started to get tachycardia and stopped selenium. My tachycardia subsided, however, I crashed completely. I never ever had such a bad crash, which manifested as terrible fatigue, joint pains, connective joint pains, loss of fingerprints...
I only can conclude that the selenium kept the virus quiet(not replicating), but as soon as I stopped it, virus started replicating as hell. You see this behaviour also with HIV+ people on ARV, and when they stop ARV's, the disease is much worse. I think it's the same effect.
Of course, you're not helped with what I'm saying. You maybe can try selenium in lower dose as I took, maybe 200Ug ? The problem is, when you have to stop, everything will come back exponentially.
Take care,
OS.
