Thanks again, Matt, for the detailed info. I don't think I can take an actual immune booster while I am on immune-suppressant plaquenil. Rheumatologist explained to me once not to do that because something or other might happen. That said - last year a few doctors told me I was setting myself up for a big mishap, being on the plaquenil and also inhaled steroid. So as of three days ago, I have stopped the plaquenil. I expect a huge flair in my auto-immune diseases as that happened when I tried to reduce the dose in the past, so we'll see. I can positively say that at least I did not opt for the TNF-blockers that were recommended. Probably be dead meat it I was taking any of those ~
